Abstract

A precoding scheme for noise whitening on inter symbol interference channels is presented. This scheme is compatible with trellis-coded modulation and unlike Tomlinson precoding allows constellation shaping. It can be used with almost any shaping scheme (including the optimal SVQ shaping) as opposed to trellis precoding which can only be used with trellis shaping. The implementation complexity of this scheme is minimal—only three times that of the noise prediction filter, and hence effective noise whitening can be achieved by using a high-order predictor.
