摘要

本文分析了一种软件定义无线电(SDR)符号同步算法在频率非选择性衰落信道下的性能。该算法在存在较大频率或相位误差的情况下运行，并显著降低了复杂性。通过仿真分析了所提出的时间估计器在频率非选择性瑞利衰落信道中的性能。结果表明，采用该算法的M-ary PAM系统的性能与具有完全同步的接收机的性能相当。并对该算法的实现方面进行了研究。

A clock recovery algorithm for software defined radios and performance analysis over a frequency nonselective fading channel

In this paper performance of a symbol synchronization algorithm for software defined radios (SDR) is analyzed over frequency nonselective fading channels. This algorithm operates in the presence of large frequency or phase errors and offers a significant reduction in complexity. With the aid of simulation, we analyze the performance of the proposed time estimator for a frequency nonselective Rayleigh fading channel for M-ary PAM modulation scheme. It is shown here that the performance of the M-ary PAM system which utilizes the proposed algorithm parallels that of a receiver with perfect synchronization. Also the implementation aspect of this algorithm is studied here.
