Abstract :
An algorithm for blind adaptive equalization of digital communication channels for QAM (quadrature amplitude modulation) signals is derived. The algorithm uses the fourth-order statistical moments of the symbol sequence explicitly. The algorithm is linear, and is fundamentally different from common gradient-type algorithms intended for the same purpose
