GSM公共信道中SCH自适应均衡解调算法研究

Study of Adaptive Equalizer for SCH of Public Channel in GSM

针对移动信道多径效应造成的严重的码间干扰（ISI）问题，研究了基于最大似然序列估计（MLSE）的GSM公共信道中SCH自适应均衡解调算法，并对这种自适应均衡解调算法在Jakes移动信道模型环境下的性能进行了分析和计算机仿真，仿真结果表明该自适应均衡解调算法能够很好地克服码问干扰（ISI）问题，性能良好。

Aiming at the intersymbol interference （ISI） of the radio signals coursed by the mobile multipath fading channel, this article makes research on the MLSE based SCH adaptive equalization algorithm in the public channel. Then the performance of the algorithm in a Jakes mobile channel environment has been simulated and investigated. Simulation results show that the algorithm can conquer the intersymbol interference （ISI） very well.
