Blind Equalization for Single Carrier Frequency Domain Equalization with Low Complexity

摘要：

A novel approach of blind constant modulusalgorithm (CMA) for single carrier frequency domainequalization is proposed to solve the application of CMAimplemehted in frequency domain,based on the constantmodulus property from frequency domain to time domain.It isillustrated that this method has lower complexity than timedomainsubspace algorithm has in broad wireless systems.Andcompared with the frequency-domain algorithm in 5,the complexity of the new idea is greatly reduced as well.In this research,the transformation of constant modulus algorithm from time domain to frequency domain is obtained under the assumption that the source signal amplitude remains 1.Therefore,the validity of equation(8)results in the conclusion that the performance of symbol error of the method would not be influenced by the transformation from time domain to frequency domain.Simulation results demonstrate it.
