中文摘要：
针对快速Raylei曲衰落信道下，逐幸存路径最大似然序列检测（MLSD）接收机中过于复杂的计算量问题和实时信道跟踪难题，综合采用了简化的Kalman信道跟踪算法和减状态的逐幸存路径（RSSE—PSP）Viterbi算法，实现了更简化的最大似然序列检测接收机．仿真结果表明，这种简化的Kalman—RSSE—PSP最大似然序列检测接收机．具有相对较低的计算复杂度，误码率性能也优于同衰落率条件下采用递归最小二乘（RLS）-RSSE—PSP算法的最大似然序列检测接收机．
英文摘要：
To overcome the high computational complexity problem of per-survivor-processing（PSP） algorithm in maximum likelihood sequence detection （MLSD） method and the real time channel tracking problem for fast Rayleigh fading channel, a reduced-state sequence estimation （RSSE） with persurvivor processing for Viterbi algorithm and reduced complexity Kalman channel tracking technique is studied in maximum likelihood sequence detection receiver. Computer simulation results show that the computational complexity of this simplified Kalman-RSSE-PSP maximum likelihood sequence detection receiver is less than recursive least square （RLS） -RSSE-PSP MLSD receiver, meanwhile its bit error rate performance is lower than RLS-RSSE-PSP MLSD receiver.
