Constant modulus algorithm assisted soft decision-feedback equalization
S. Vlahoyiannatos, Lajos Hanzo · 2002
A new blind equalizer is proposed, extending the well-known constant modulus algorithm (CMA), which is based on a finite impulse response (FIR) filter, to an infinite impulse response (IIR) scheme. This equalizer is capable of equalizing channels having zeros on the unit circle with better accuracy than that of the classic CMA, while maintaining a similar complexity.
