FREQUENCY-DOMAIN IMPLEMENTATIONS OF THE
C.K. Chan, J. John · 1989
The constant modulus algorithm (CMA) is one method of blind equalization that compensates for channel distortion in digital communication systems. In this paper. we present several efficient block implementations of CMA that are based on frequency-domain techniques. These tech- niques implement either a linear M circular convolution. and they use dimete Fourier transform (Dm filter banks and multirate signal processing.
