摘要

本文推导了衰落信道中未知信道参数情况下相移键控信号多信道分集合并的最大似然序列估计算法，并在此最优方案的基础上提出了两个新的次最优维特比算法．将该算法用于直扩系统的ＲＡＫＥ接收机的模拟结果表明，对ＤＱＰＳＫ和编码的ＱＰＳＫ信号的接收性能与理想接收十分接近

Abstract

In this paper

we propose the maximum likelihood sequence estimation of phase modulated diversity combining system without knowledge of channel parameter

together with a suboptimum modified Viterbi algorithm using this principle.The algorithm is applied to RAKE receiver without channel estimation

and the simulation results show near optimum performance for uncoded DQPSK and coded QPSK signals

which recovers the power loss due to differential reception.
