Abstract

Abstract

This paper studies the estimation of slow time-varying frequency-selective MIMO wireless channel, which is described by the parameter of harmonic fitting model and presents a method of channel estimation based on harmonic retrieval of vector sequence and LS method with nonlinear constraints using training sequence. The method applied in this paper uses the identic sequence instead of chirp sequence. The simulation shows that this method has more simple training sequence and better estimation performance with same SNR in contrast to the method applying chirp sequence as training signals.
