A novel construction function blind equalization algorithm based on QAM signals
XU Chang-qing · Information technology newsletter · 2004
Based on QAM modulation and constant modulus algorithm(CMA), a novel blind equalization algorithm, the construction function(CF) algorithm is proposed. Through constructing a function which makes the values to be zero in the amplitude value points of QAM signals, CF algorithm improves the convergence speed and accuracy by using exact information of QAM signals. Computer simulations demonstrate that the CF algorithm can overcome the phase ambiguity (or phase offset)problem of QAM signals and so has good (performances.)
