文中基于最大似然估计理论(M LE)提出了一种新颖的解决信道估计、符号定时和频率偏移的联合算法,并给出了该算法的一种实现方案。利用计算机对文中提出的算法与Schm id l&Cox算法在符号定时、频偏纠正和信道估计性能方面做了比较分析。当频偏步进值选取为0.05Δf时,该算法优于传统的方法。 In this paper, a new joint algorithm to solve channel estimation, symbol timing and frequency offset is proposed based on Maximum Likelihood Estimation (MLE), and an implementation of this algorithm is given. The algorithms proposed in this paper are compared with the Schmid id & Cox algorithm in the aspects of symbol timing, frequency offset correction and channel estimation performance. The algorithm is superior to the traditional method when the frequency offset step value is 0.05Δf.
