Abstract To overcome the drawbacks of samples impoverishment, an evolutionary particle filtering algorithm is proposed for blind signal detection over flat Rayleigh fading channels whose model coefficients are unknown. During the resampling of particle filtering, evolutionary programming is used. The evolutionary particle filtering algorithm is adopted to overcome the drawbacks of samples, which forms into a blind detection based in evolutionary particle filtering. It is shown through simulations that the proposed particle filtering detector maintains comparable performance with mixture Kalman filter with known model coefficients.
