A High Performance Blind Adaptive Filtering Algorithm
نویسنده
چکیده
Recently a dithered signed-error constant modulus algorithm (DSE-CMA) has been proposed for the purpose of low complexity implementation of constant modulus algorithm (CMA), which is widely used for blind adaptive filtering due to its LMS-like desirable robustness properties. Despite the fact that this algorithm has robustness properties closely resembling those of CMA, it is very slow in convergence. In this work, we present a simple modification of DSE-CMA using a variable step size that results in faster convergence while preserves the low computational complexity and robustness properties of the DSE-CMA algorithm. Key-Words: LMS algorithm, adaptive filters, dithered signed-error, constant modulus algorithm
