中文摘要：

通信系统中维特比均衡器常用来克服频率选择性失真,但其计算的复杂度和占用的硬件资源一直是其应用时需要解决的关键问题。介绍了采用维特比均衡方法的GMSK解调系统,对其软判决的算法进行了分析,并采用ASIC设计方法,对其输入存储量,幸存路径计算复杂度,输出译码复杂度等进行了优化,减少了硬件实现的代价。

英文摘要：

Viterbi equalizer is typically implemented to combat frequency-selective distortion in communication systems, and the reduction of computation complexity and cost is the key problem. Viterbi algorithm used in GMSK demodulation system is analyzed and implemented. The proposed structure could successfully realize the system performance, and reduce the system cost and hardware complexity.
