摘要

本文介绍了一种采用改进的双表输出Viterbi算法(LOVA)的Viterbi解码器的实现，该解码器用于码分多址(CDMA)移动站中可变数据速率帧的解码。它执行卷积码k=9，率=1/2的解码为下降，一半，四分之一，和第八数据速率帧。该Viterbi解码器是用于is -95蜂窝和个人通信系统(PCS)移动终端的CDMA基带处理器的一部分。

Variable data rate Viterbi decoder with modified LOVA algorithm

This paper describes the implementation of a Viterbi decoder with a modified list-of-two List Output Viterbi Algorithm (LOVA) which is used to decode variable data rate frames in Code Division Multiple Access (CDMA) mobile stations. It performs the decoding of convolutional code k=9, rate=1/2 for fall, half, quarter, and eighth data rate frames. This Viterbi decoder is a part of a CDMA base-band processor used in an IS-95 cellular and Personal Communication System (PCS) mobile terminal.
