In this paper, the signal model of baseband equalization communication system is described. Three typical Bussgang equalizers based on this model are studied: constant modulus algorithm (CMA), Sato and direct decision (DD) equalizer. The performance simulation results related to the algorithm are given. The simulation results show that the CMA equalizer can provide better BER performance and faster convergence than Sato and DD equalizers.
