Wen Si-yuan · Procedia Engineering · 2011
For blind equalization of high-order quadrature amplitude modulation (QAM) signals, A dual-mode multi-modulus algorithm (DM- MMA) and a stop-and-go dual-mode multi-modulus algorithm (SAG-DMMMA) are proposed. Through Simulation, compared with the recently introduced multi-modulus algorithm, verified the proposed blind equalization algorithms have faster convergence speed and smaller steady-state mean square error.
