Adaptive Minimum BER Channel Equalisation in DMT Systems

"In this paper we investigate the use of adap- tive minimum bit error rate (MBER) algorithms for channel equalisation in Discrete Multitone (DMT) systems. These algorithms approximate the bit error rate (BER) from training data using linear equaliser structures operating in the frequency domain. A comparative analysis of DMT systems with linear equalisers, employing minimum mean squared error (MMSE) and MBER algorithms is carried out. Computer simulation experiments show that the MBER algorithms outperform the LMS approach and can save transmitting power for the same BER performance."
