Optimal Channel Detection for Nonbinary Coded Partial Response Channels
DOI:10.1109/TCOMM.2009.07.060615.png)
摘要
En 中文
We derive a recursive algorithm to compute the joint maximum a posteriori probabilities of p consecutive bits on partial response channels. This channel detector is optimal for nonbinary soft-iterative decoding with multiple channel iterations. It is validated on a nonbinary low-density parity-check coded perpendicular magnetic recording channel.
