A novel variable step size constant modulus algorithm employing cross correlation between channel output and error signal

Ali ÖZEN

A novel variable step size constant modulus algorithm (VSS-CMA) employing cross correlation between channel output and error signal has been proposed as a solution to the problem of slow convergence of CMA algorithm. The new algorithm resolves the conflict between the convergence rate and low steady state error of the fixed step-size conventional CMA algorithm. Computer simulations have been performed to verify the performance of the proposed method in frequency selective Rayleigh fading channels. The proposed technique has been compared with the popular non-blind equalizer, Least Mean Squares ...Daha fazlası

A Novel Variable Step Size Adjustment Method Based on Autocorrelation of Error Signal for the Constant Modulus Blind Equalization Algorithm

Ali ÖZEN

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 VSSCMAs 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 al ...Daha fazlası
