Abstract

Abstract

A novel Volterra equalizer based on minimum bit error rate principle is proposed in this paper for interference suppression in communications. The Volterra kernels are estimated based on minimum bit error rate principle and this is different from the previous literatures which are based on minimum mean square error. Simulation results show that when extended binary phase shifting keying signals are contaminated by relatively strong narrowband interference, the performance of matched filters and linear equalizers degenerate rapidly, but Volterra equalizers based on minimum bit error rate provide very low bit error rate, and their performance is also far better than that of Volterra equalizers based on minimum mean square error. Furthermore, it is found that odd and third-order Volterra equalizers are more practical than other order Volterra equalizers.
