A robust RLS detector on tracing wireless channel information

This paper studies the estimation of the fading channel in the present of the impulse noise. The impulse noise suppression function was deduced to improve the ability of suppressing the impulse noise. The analysis has proven that the modified algorithm still meets the linear equation. In addition, this paper applies the modified recursive least square (RLS) algorithm to estimate the impulse response vector in the time-varying fading channel. The simulation results show that the modified RLS algorithm is more robust against consecutive impulse noise and have better convergence ability than conventional RLS.
