Abstract

A novel adaptive training algorithm for joint channel shortening and radio frequency interference suppression is proposed for discrete multi-tone (DMT). Using an equation-error based approach, it both shortens the channel impulse response (CIR) and removes the interferences using a short-length FIR filter. The technique is effective in performance yet has very low complexity in implementation. Numerical simulation results for two CSA loops are presented. Theoretical derivation is also furnished to justify the method.
