Abstract

Recursive Levenberg-Marquardt (RLM) algorithm is presented for per-tone equalisers in discrete multitone systems. We introduce how to formulate the proposed RLM algorithm for non-linear adaptive filter. Simulation results show that the proposed RLM algorithm can improve bit rate performance and Signal to Noise Ratio improvement as compared to the existing recursive least squares-based algorithms and matched filter bound.
