Abstract :
This paper introduces a filtered-x least-mean-square (FXLMS) based sub-band adaptive algorithm with error path delay compensation. Our algorithm avoids the signal path delay while compensating for the error path delay, thus increasing system stability. Simulation results are presented to demonstrate experimentally the efficiency of this new adaptive algorithm.
