非線性信道判決反饋均衡器
A DECISION FEEDBACK EQUALIZER FOR NON-LINEAR CHANNELS
-
摘要: 本文針對嚴重線性失真、輕度非線性失真的信道提出了一種簡單實用的非線性信道判決反饋均衡器。它是一個將關聯模型非線性信道均衡器與線性信道判決反饋均衡器相結合的產物。對典型的非線性信道模型所做的模擬試驗表明,該均衡器不僅簡單實用、便于實時處理,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. -
