Study Of Synchronization Techniques In UWB And A Implementation Of Synchronization On FPGA

Since the Ultra Wideband (UWB) wireless communication has lots of advantages such as high data transmission rate, low power consumption, high precision location identification and inherently exceptional multipath immunity and so on, it has been the subject of extensive research in the short-range wireless communication area. But there are still some key problems need to be solved before the UWB technology comes into actual use, and one of these key points is synchronization and hardware implementation. It requires not only a good performance, but also a simple structure.In this thesis,the basic theory of UWB communication is introduced at first. The system model and the modulation technology is then analyzed in detail, also the UWB channel model is discussed. Many synchronization schemes are illustrated and compared in succession.Then a zero correlation zone(ZCZ) sequence is constructed as a training sequence on adaptation algorithm. Its performance of autocorrelation and cross-correlation is very ideal. The simulation results demonstrate that the methods can effectively improve the performance of synchronization.On the hardware side, a ZCZ sequence frame synchronization is statemented and realizationed on FPGA.The recognizer has been designed and simulated by DSP Builder.Then ,it is programmed to FPGA,in order to do hardware simulation.The result of simulation indicated this plan is accurately and feasiblely.
