A novel noise adjustment technique for MIMO-OFDM system based on fuzzy-based adaptive method

Abstract

In this paper, we have presented the novel noise adjustment technique for MIMO-OFDM system on fast time-varying multipath fading channel using fuzzy-based method. The investigated parameters are bit error rate, size of the antenna, and the types of modulation method. We have proposed the method with respect to Rayleigh fading channel. We have also compared the proposed fuzzy-based adaptive method with the conventional SKF, DKF, and Nonlinear Kalman filter method. In the proposed method, the lowest value of bit error rate is achieved compared to conventional method.
