ZU Jia-kui · Kongzhi yu juece · 2004
Based on non-singleton fuzzy logic theories, a method is presented to design adaptive fuzzy filters. The (designing) process is described in detail and structure identification and parameter optimization are especially (emphasized.) An adaptive non-singleton fuzzy filter is investigated and analyzed for nonlinear communications channel (equalization) to solve its stability of digital transmission. Simulation results show that the proposed method can resist time-varied factors and stochastic noise, and solve nonlinear aberration effectively. It is strongly adaptive to improve correctness and efficiency of digital communication channel.
