Abstract :
Recently, Various blind channel equalization techniques for chaotic communication systems have been developed. However, in most of these studies communication channel is assumed to be single-input single-output (SISO) system. To the best of our knowledge, there is no study about blind equalization of multiple-input multiple-output (MIMO) channel case. In this study, an adaptive blind channel equalization algorithm for multiple-input single-output (MISO) chaotic communication system has been proposed. The channel is modelled as a MIMO finite impulse response (FIR) system and the equalizer is designed as a MISO FIR filter. The nonlinear predictability of a chaotic signal is exploited to derive the algorithm and the equalizer coefficients are updated by the proposed algorithm.
