PAM系统中基于最大似然估计的符号同步技术

Study on the Symbol Synchronization Based on Maximun Likelihood Estimation in PAM Communication System

探讨了二进制基带 PAM通信系统中的符号同步问题。给出了该系统模型 ,推导了 PAM通信系统符号同步误差对收端误码率的影响。并在最大似然估计基础上 ,讨论了最优符号同步相位估计的二分法 ;最后 。

Symbol synchronization in binary baseband PAM communication system is discussed in this paper. The system model is introduced and the probability of error in receiver as a function of symbol synchronization error is deduced.The bisection search algorithm based on maximun likelihood estimation for the estimation of the optimun timing phase is also developed. then, suggestion for further work is given by the authors.
