| 摘 要： | 1. INTRODUCTION Badly nonlinear distortion often occurs in high-speed wireless digital transmission systems, which calls for an adaptive nonlinear equalizer capable of counteracti- ng deep fading. There are two types of nonlinear equalizers: maximum-likelihood sequence equalizer (MLSE) and decision-feedback equalizer (DFE). Bec- ause of intense computation and enormous storage, MLSE isn’t suitable for application. DFE is widely used due to its simple structure, but the forward and f…

| Abstract: | A new equalization method is proposed in this paper for severely nonlinear distorted channels. The structure of decision feedback is adopted for the non-singleton fuzzy regular neural network that is trained by gradient-descent algorithm. The model shows a much better performance on anti-jamming and nonlinear classification, and simulation is carried out to compare this method with other nonlinear channel equalization methods. The results show the method has the least bit error rate (BER). |
