关于收发机失真信道的一点注记

A Remark on Channels with Transceiver Distortion

Wenyi Zhang

摘要:

利用高斯输入分布下的广义互信息(GMI)和最近邻译码,研究了具有收发机失真的信道上的信息传输。一个规范的收发器结构,其中的信道输出是由一个最小均方误差估计解码前处理建立最大化的GMI,和著名的Bussgang的分解被证明是一个启发式的,是一致的线性输出处理下的GMI。

英文摘要:

Information transmission over channels with transceiver distortion is investigated via generalized mutual information (GMI) under Gaussian input distribution and nearest-neighbor decoding. A canonical transceiver structure in which the channel output is processed by a minimum mean-squared error estimator before decoding is established to maximize the GMI, and the well-known Bussgang's decomposition is shown to be a heuristic that is consistent with the GMI under linear output processing.
