-
摘要: 本文针对严重线性失真、轻度非线性失真的信道提出了一种简单实用的非线性信道判决反馈均衡器。它是一个将关联模型非线性信道均衡器与线性信道判决反馈均衡器相结合的产物。对典型的非线性信道模型所做的模拟试验表明,该均衡器不仅简单实用、便于实时处理,而且均衡性能得到较大的改善。

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. -
