A step-varied CMA blind equalization algorithm based on autocorrelation of error signal
Xinyun Qiu, Yuan Gao · Chinese Control Conference · 2010
A step-varied blind equilibrium algorithm is proposed in this paper, in which step is controlled by error signal pointing to the problem caused by step-constant blind equilibrium algorithm. The proposed algorithm regulates equalizer parameter in real time by varied step. Thus, time-variant channel can be equilibrated rapidly and anti-jamming is greatly improved in low SNR communication. At last, the equalizer is superior to the equalizer based on step-constant CMA algorithm in common channel by simulation.
