非线性均衡以前被证明是有益的记录通道与非线性和信号相关的噪声。在这项工作中，我们研究了两种类型的简化的非线性滤波器架构，适合于VLSI实现。由于简化的性能损失是不显着的，在大多数情况下，相比的信噪比增益实现非线性均衡。在一种简化形式中，消除了对全乘法的需要，而在另一种简化形式中，显著减少了原始非线性滤波器架构中的乘法次数。实验和模拟数据的工作。
Nonlinear equalization was previously shown to be beneficial for recording channels with nonlinearities and signal-dependent noise. In this work, we study two types of simplified nonlinear filter architectures that are suitable for VLSI implementation. The performance loss due to the simplifications are not significant in most cases, compared to the signal-to-noise ratio gain achieved by nonlinear equalization. In one form of simplification the need for full multiplications is eliminated and in the other the number of multiplications in the original nonlinear filter architecture is reduced significantly. Work on experimental and simulated data are presented.
