The ultra-wide band technology, which was called Impulse Radio, was originally applied in military field. At present, more and more attention is paid to this short distance communication technology along with the FCC's agreement of its civil use. The current ultra-wide band includes two types: multi-band OFDM (MB-OFDM UWB) and direct sequence spread spectrum (DS-UWB). Because MB-OFDM UWB, which is quite mature, is not essentially different from OFDM technology, it is in dominant position in the competition. However, DS-UWB has commercial potential because of its low power and simple equipment and so on.At present, both of these two kinds of UWB are facing the same problem on how to coexistent with the existing narrow band wireless communication system. Compared with MB-OFDM UWB, the interference problem of DS-UWB is more serious, which is mainly because that the interference origin is complex and the solutions are limited. Based on DS-UWB, this article discusses DS-UWB interference origin and the frequency domain solution.

The Best Holiday I Have Ever Had
The best holiday I have ever had was in America. Here is the best northface outlet!I went there with my family last year during my summer vacation.Where can you find this chi straightener? We stayed in San Francisco and Las Vegas. It was really great. The air is better than in Taiwan and we had a lot of fun at night, like seeing the white tiger show and some other hotel shows. We also went to the beach and to Seaworld. I liked to play ball on the sand and I saw many kinds of fish at Seaworld. But the best part of the holiday was Disney Land. It was cool! Do you need cheap ralph lauren polo shirts?We saw a 3D movie and took photos with Mickey and Mini. However, in America, the food was terrible! But when we were there we bought some clothes and learned something about their culture, so I would really like to go back again.

What should the get-rich-quicks do to their fellow human beings? Some of them show no compassion for the needy; some even look down upon the poor with snobbish eyes. Where can I get nike running shoes?They are not conscious that it is their social obligation and moral duty to make the present world a better place for their compatriots to live by offering timely help to them. The wide gap between the rich and the poor is a threat to the stability of society, therefore it must be narrowed. How much do these cheap straighteners cost?Any well-educated person with common sense can grasp the truth that a society where people show friendship, love and kindness to one another is a good progressive society. Conversely, a world filled with hostility, hatred and cruelty due to wide gap between the rich and the poor is a backward and unsafe world. Everyone wants to get cheap Lacoste POLO Shirts.Dangers lie in ambush and are bound to erupt like a volcano. People all desire for a good society where the majority of population can lead a well-to-do life and live in harmoney with friendship, love and kindness. The needy are well attended to.

Cold Isolation among Modern People
Nowadays, the phenomenon of globalization is becoming more and more popular, but it seems that the information-share doesn’t make the north face jackets smaller. Modern people have a feeling that they are becoming more and more distant from each other and a feeling of isolation among people exists everywhere.It is undeniable that the relation between people becomes more and more chilly. cheap north face jackets live under a greater tension compared with past days. They are busy in struggling for many things such as continuous promotion in job, bigger house in life, good education for children and so on, so they have less time to communicate with each other. More and more people are living in urban areas, where life is in a quick rhythm. In virtue of fierce competition, city dwellers have to be hardworking in order to keep up with the steps of city life. Weighty pressure prevents them of a casual way of life. Everyone is busy in his own things all the time and the love and care for others disappear.northface jackets, living in apartments in different blocks, people are isolated from each other. It is not convenient for them to meet each other freely. In some sense, life is cruel. Even living in apartments of the same building, the warm care between neighbors become rare, what people care is confined into their little apartment. It is not unwonted that neighbors regard each other as strangers, though they live adjoiningly for a long time. So maybe I shouldn’t feel surprising when I heard that Zhang Ailing, my favorite authoress, died in her apartment lonely and her death was found days later. It seems that the cold competition, the cold cement buildings and the mechanic city pace make people more and more cold-blooded. Modern people would rather entertain themselves in the way of watching TV programs or VCD staying at home off job than meeting and talking to others. Modern people have few chances or avoid such chances unconscious to meet each other and thus a feeing of isolation arises.
