超宽带(UWB)以其传输速率高、抗多径和抗干扰能力强等优点,在短距多址无线通信中良好的应用前景而引起广泛研究。文章提出了一种基于ML的UWB同步接收方案,采用相关器与ML估计准则结合在一起实现同步。仿真结果表明:捕获的导频序列M越长和估计的支路数越多,误码率就越低。 UWB (UWB) has been widely studied due to its high transmission rate, anti-multipath and anti-interference ability, and its good application in short-range multiple access wireless communication. In this paper, a UWB synchronization receiving scheme based on ML is proposed, and the correlator and ML estimation criterion are used to realize the synchronization. Simulation results show that the longer the pilot sequence M is captured and the larger the estimated number of branches, the lower the bit error rate.
