Application of channel matched filters and direct coefficients calculation for low complexity high bit rate equalisation

For high data rate mobile communication systems, because of the channel time-delay-spread, the equalisers are critical for combating inter-symbol-interference (ISI). The required time for equalisation training is one of the main limitations affecting the data rate and throughput. This study introduces a new method for equalisation using a channel matched filter (CMF) which combines a speed of coefficient calculation comparable with the simple least-mean-square (LMS) algorithm, with an equaliser filter performance which can exceed that of the recursive-least squares (RLS) algorithm. Synchronisation, channel tracking and frequency offset problems are also considered
