非線性信道判決反饋均衡器
A DECISION FEEDBACK EQUALIZER FOR NON-LINEAR CHANNELS
-
摘要: 本文針對(duì)嚴(yán)重線性失真、輕度非線性失真的信道提出了一種簡(jiǎn)單實(shí)用的非線性信道判決反饋均衡器。它是一個(gè)將關(guān)聯(lián)模型非線性信道均衡器與線性信道判決反饋均衡器相結(jié)合的產(chǎn)物。對(duì)典型的非線性信道模型所做的模擬試驗(yàn)表明,該均衡器不僅簡(jiǎn)單實(shí)用、便于實(shí)時(shí)處理,而且均衡性能得到較大的改善。

Abstract: A simple and useful decision feedback equalizer used for non-linear channels with severe linear distortion and mild non-linear distortion is proposed. It is a combination of a non-linear channel equalizer based on connectionist model and a common decision feedback equalizer for linear channels. For a typical non-linear channel model it is shown by simulation that the equalization performances of the proposed equalizer are improved significantly. -
