摘要

提出了一种用于CDMA信道上矢量量化的最优软解码器。它利用先验的信源信息和信道特性来对抗信道噪声和多用户干扰。还考虑了较低复杂度的最优解码器版本。仿真结果表明，软解码器优于ml检测加查表VQ解码方案。

Vector quantization over a CDMA channel using soft multiuser decoding

The optimal soft decoder for vector quantization over a CDMA channel is presented. It utilizes a-priori source information and channel characteristics to combat channel noise and multiuser interference. Versions of the optimal decoder with lower complexity are also considered. Simulations demonstrate that the soft decoder outperforms the scheme that uses ML-detection plus table look-up VQ decoding.
