communication systems

The main content of this thesis is researching the acquisition algorithms of synchronization in IR-UWB(Impulse-Radio Ultra-WideBand)communication systems. The advantages of UWB systems, such as low cost, low power waste, low complexity and high data rate, attract lots of interesting in both academia and industry recently.Synchronization between transmitter and receiver is the key technology in communication systems, especially in IR-UWB communication system which usually applied in burst communications. IR-UWB systems use discrete ultra narrow pulse series to carry information, which is different from other wireless communication systems. Firstly, due to the power limit of FCC(Federal Communication Commission), the power of transmitted signals is very low, and the power spectral density exist below the noise level at the receiver because of the huge band width caused by ultra narrow pulses. It will spend the receiver a long time to make reliable decision. Secondly, it is difficult to complete the acquisition of the received signals, for the search space is very large due to the fine time resolution caused by the low duty cycle of the ultra narrow pulses.

We may, and frequently do, feel much trouble trying to get adapted to the weather, hot or cold. Therefore, if I could, I would invent clothes that can be flexible to all kinds of weather automatically.The texture of clothing should be excellent and delicate enough to resist heat or cold. While it is too hot, the specially-made clothes would lower the temperature to a satisfactory extent.
