摘要

本文介绍了一种用于EDGE、WCDMA和CDMA2k卷积码的多标准信道解码器的VLSI实现。新架构采用MAP算法进行卷积解码，支持软输出。解码器是为基站应用而设计的。在时钟频率为200mhz时，WCDMA和CDMA2k解码器的最大吞吐量为16mbps, EDGE解码器的最大吞吐量为70mbps。

A multi-standard channel-decoder for base-station applications

In this paper, a VLSI implementation of a multi-standard channel-decoder for EDGE, WCDMA, and CDMA2k convolutional-codes is presented. The new architecture employs the MAP algorithm for convolutional decoding to support soft-outputs. The decoder is designed for base-station applications. The maximum throughput of the decoder is 16 Mbps for WCDMA and CDMA2k, and 70 Mbps for EDGE, at a clock frequency of 200 MHz.
