摘要

导频符号辅助调制(PSAM)是一种在移动通信中通过周期性地在数据流中插入已知符号来减少衰落影响的方法。接收机使用这些导频符号来推导其幅度和相位参考。该程序的一个方面在文献中没有得到太多关注，即接收器用于定位导频符号的方法。本文通过研究M-QAM数据符号集和PSK导频序列的最优和次优帧同步技术来满足这一需求。

Frame synchronization for PSAM on Rayleigh fading channels

Pilot symbol assisted modulation (PSAM) is a method to reduce the effects of fading in mobile communications by periodically inserting known symbols in the data stream. The receiver uses these pilot symbols to derive its amplitude and phase reference. One aspect of this procedure which has not received much attention in the literature is the method used by the receiver to locate the pilot symbols. This paper satisfies that need by investigating optimum and sub-optimum frame synchronization techniques for the case of an M-QAM data symbol set and a PSK pilot sequence.
