摘要
W-CDMA系统中采用约束长度为9的卷积编码作为信道编码方案之一,维特比译码器是被一种人们广泛采用的卷积编码的解码器;本文通过分析卷积编码及维特比译码的过程,介绍一种适合WCDMA系统中软判决维特比译码器实现的硬件结构。
W - CDMA System adopts Convolutional Code - Constranit length of 9 as one of the Channel - Coding Schemes. In practice, Viterbi Decoder is a popular decoder for Convolutional code. This article analyzes the Convolutional coding and Viterbi decoding and presents a hardware structure of the soft - decision Viterbi Decoder suited for W - CDMA System.
