二维的码间干扰的先验最小均方误差均衡

Minimum Mean-Square-Error Equalization using Priors for Two-Dimensional Intersymbol Interference

N. Singla, J. A. O'Sullivan

摘要:

联合均衡和解码方案描述了二维的【形】符号间干扰(ISI)信道。均衡使用最小均方误差(MMSE)准则来执行。低密度奇偶校验码用于纠错。MMSE方案是Tuechler等人(2002)针对一维ISI信道提出的方案的扩展。外部信息传递图,密度演化,和比特出错率与信噪比曲线被用来研究该计划的性能。

英文摘要:

Joint equalization and decoding schemes are described for two-dimensional intersymbol interference (ISI) channels. Equalization is performed using the minimum mean-square-error (MMSE) criterion. Low-density parity-check codes are used for error correction. The MMSE schemes are the extension of those proposed by Tuechler et al. (2002) for one-dimensional ISI channels. Extrinsic information transfer charts, density evolution, and bit-error rate versus signal-to-noise ratio curves are used to study the performance of the schemes.
