| 摘 要： | 推导符号定时偏差对接收端误码率的影响。在最大似然估计基础上,讨论最佳符号定时恢复的内插迭代二分算法,并在存在频偏的条件下对该算法进行了仿真,仿真结果表明,即使存在频偏时,只要简单使用差分运算,就可以达到设计要求的性能。

| Abstract: | This paper deduce the probability of error in receiver as a function of symbol timing offset. The interpolated-bisection search algorithm based on maximum likelihood estimation for estimation of optimum symbol timing recovery is developed and its performance is investigated by simulation. The simulation results show the novel algorithms can achieve a better performance either with frequency offset only using difference operation. |
