Evolutionary algorithms in iterative channel estimation for MLSD application

This article presents iterative estimation method with usage of evolutionary algorithms of the narrowband propagation channel impulse response, which can be used in reception based on maximum likehood sequence detection (MLSD). This method relies on minimization of an additional objective function, based on the knowledge of frequency characteristics of the narrowband channel. In the article, data reception in maximum likehood sequence detection sense, conception of the iterative channel impulse response estimation and simulation results in MATLAB/Simulink enviroment have been presented.
