Channel Estimation and Equalization Using Higher Order Cumulant and Constant Modulus Algorithms

This paper present the problem of blind channel estimation of a non-minimum phase system using three algorithms. These algorithms play an important role for blindly parameters channel estimation. Thus studying the problem of blind channel equalization based on the presented algorithm and the filter adaptive equalizer. The simulation results in noisy environment and for different SNR values, demonstrate that the proposed algorithm is more powerful than other algorithms. In addition the proposed algorithm is more powerful in comparison to Constant Modulus Algorithm (CMA) at the blind channel equalization.
