Electronic Dispersion Compensation in High Speed Optical Transmission System

In this thesis, the development of dispersion compensation in optical domain and current researches status of EDC is illustrated. Dispersion compensation in both optical and electrical domains has been compared. Also, the development of new modulation technique is introduced.Principle of equalizer and adaptive algorithm related has been analyzed. After study about performance of 10Gbit/s NRZ optical system, we find out that the more the tap equalizer used, the better performance could be got, while significant improvement couldn't be attained when the number of tap equalizer is bigger than a certain value.Simulation of intensity modulation and phase modulation is accomplished based on the analysis of modulation principle. Spectrum and back-to-back eye diagram are analyzed according to simulation results. EOP is used for the evaluation of system performance and dispersion tolerance of different modulation.Finally, we built several different models for different modulation with FFE and DFE. According to simulation results given by these models, the right equalizers for different models had been chosen. The performance of the above equalizers in intensity and phase modulation had been compared and analyzed theoretically.

Memories of My Mother

"long, long ago, there was an island in the distant sea,where lived a fairy who was said be able to make a child lovely and bright. one day, ..." as the story went on, mumps voice grew fainter and fainter, when she gently looked down at me.then a melodious song came into my ear as if music made by the angels flying in the faraway sky. gradually, mom's smile dimmed, and her glittering eyes were just like the brightest stars on the dark blue curtain of night...
　　countless nights had passed in this way during my infancy. Where can I get nike running shoes?in my naive heart, mother's voice was deeper and softer than the nightingale. even now i still remember quite clearly that cradlesong she used to sing before i fell asleep.How much do these cheap straighteners cost? those old melodies still sound so good to me, as they melt the years away.to me, mother's companionship was the most important thing in my childhood.
　　mother is an incurable romantic, passionately in love with life and with the mystery of the universe. she taught me to open up all the channels of my senses to touch and feel what lies all a round me, and discovered with me the beauty of nature, the joy,excitement and mystery of the new and the unknown. Everyone wants to get cheap Lacoste POLO Shirts.she is quite at home in literature because of her active and imaginative mind. every new experience, every new discovery concerning the world could delight her. www•
　　i went off to college, but mum is still always in my memory. i could hear her voice every time i fell short in anything.from breast to cradle to reassuring hug, mum has shared all the happiness and depression of mine. however, she never expressed herself. upon my entry into university, when she and father were going back home, she hurriedly turned back to run along, even without a look at me. i knew she dared not, for fear that tears should fall down in my presence. this separation would last nearly five months during which she could not see me. she was just trying to stop me from seeing her crying. i was refraining myself, too, because the long time living with her had made me an exact person like her. later, father told me she kept wiping her eyes on the bus to the railway station. i knew that, because i love you, mum, and you already knew that too.

The Tipping Point

For Hush Puppies - the classic American brushed-suede shoes with lightweight crepe sole - the Tipping Point came somewhere between late 1994 and early 1995. Lacoste Shirts are waiting for you here! The brand had been all but dead until that point. Sales were down to 30,000 pairs a year, mostly to backwoods outlets and small-town family stores. Wolverine, the company that makes Hush Puppies, was thinking of phasing out the shoes that made them famous. But then something strange happened. At a fashion shoot, two Hush Puppies executives - Owen Baxter and Geoffrey Lewis - ran into a stylist from New York who told them that the Vlasic Hush Puppies had suddenly become hip in the clubs and bars of downtown Manhattan. "We were being told," Baxter recalls, "that there were resale shops in the Village, in Soho, where the shoes were being sold. People were going to the Ma and Pa stores, the little stores that still carried them, and buying them up." Baxter and Lewis were baffled at first. It made no sense to them that shoes that were so obviously out of fashion could make a comeback. ...
By the fall of 1995, things began to happen in a rush. I feel the need-the need for cheap Wholesale nike shoes！First the designer John Bartlett called. He wanted to use Hush Puppies in his spring collection. Then another Manhattan designer, Anna Sui, called, wanting shoes for her show as well. Cheap Nike shoes are very nice here! In Los Angeles, the designer Joel Fitzgerald put a twenty-five-foot inflatable basset hound - the symbol of the Hush Puppies brand - on the roof of his Hollywood store and gutted an adjoining art gallery to turn it into a Hush Puppies boutique. While he was still painting and putting up shelves, the actor Pee-wee Herman walked in and asked for a couple of pairs. "It was total word of mouth," Fitzgerald remembers.
In 1995, the company sold 430,000 pairs of the classic Hush Puppies, and the next year it sold four times that, and the year after that still more, until Hush Puppies were once again a staple in the wardrobe of the young American male ...
Hush Puppies had suddenly exploded, and it all started with a handful of kids in the East Village and Soho".

Walk Light and Harmony

With light above, we can walk steady and brave. With care and love, a kid can develop a happy childhood. But for rear children, their childhood is like walk with little light as their parents have to leave them behind for the city to work. When a normal happy childhood sounds like but a fairy tale for them, can we expect great harmony in our society, our big family and our next generations?Just get ralph lauren polo shirts!As many of you may have seen on CCTV during last spring festival, the story of an emotional journey of a migrant family really touched me to the bottom of my heart. These are my cheap northface jackets!On the stage, a migrant couple were presented to the audience by the famous host-Cui Yongyuan together with the chairwoman of National Women’s Association. The Couple couldn’t have gone back home for the New Year to be with their son because of their duties at a restaurant in Beijing. You can own those chi straighteners.When the host read an article by their son that he missed his mother dearly, the mother bursted into tears.
As the host finished his reading, the son appeared on the stage dramatically. But more dramatic was what their son said: he understood his parents had to leave him behind for city to give him a better future, however, when he grew up, he would rather stay with his own children in the country side than go to a city to work without his children.
These words expose us a common problem of rear children. Acutely these young hearts lack parental tender loving care. Here is the frightening statistics: more than 20million rural children in our countryside are living without their parents by their side. Worse still, these children tend to develop personal disorders, with 3 types commonly seen. First the silent and premature type, shaped by tough experience or hardship from an early age. Second, the dominating and violent type brought up and spoiled by grandparents with little self-discipline. Third, the wild type, neglected with no due care from any relatives.
Fortunately our government has taken initiatives to address this problem as so many migrant workers have made such a big sacrifice for our four modernizations. the chairwoman of National Women’s Association remarked: schools have been set up for migrant workers near their community in the city so that children can come to live with their parents in the city. Volunteers have been recruited to help rear children with their daily life and psychological problems.
But do you think these simple measures are enough to bring happiness to rural children in a new century and bring harmony to our society? Unfortunately, still only a fraction of the 20 million rear children can enjoy this new found happiness. There is so much to be done for these 20 million rear children.
The darkness and loneliness of a journey can be ignored with flowers and songs along the road. So can be our help and support to the walk of a rear child. Let’s join with their parents to create light for their walking, to bring back their innocence and happiness, and to contribute to the harmony of our society, our big family and our next generations.
