Özet

A novel variable step size constant modulus algorithm (VSS-CMA) based on autocorrelation of error signal has been proposed to improve the weakness of previous VSS-CMAs for application to blind equalization in this paper. Computer simulations have been performed to illustrate the performance of the proposed method in frequency selective Rayleigh fading channels. The obtained simulation results using WiMAX (IEEE 802.16-2004) radio standard have demonstrated that the proposed VSS-CMA algorithm has considerably better performance than conventional CMA, normalized CMA (NCMA) and the other VSS-CMA algorithms.
