Abstract

In this paper we present a new decoder for Tomlinson-Harashima precdoded (THP) signals, which is used on linear Gaussian channel with inter symbol interference. While the transmitter is not modified, the receiver modulo operation is replaced with a post priori probability (APP) module, which we term as Enhanced modulo (EMOD). The EMOD accept apriori probabilities, making it suitable for turbo operation when the THP is coded. The new scheme is much more complex than simple modulo operation and in addition induces delay. Its complexity depends exponentially on channel length. However, a large gain in performance may be obtained. The scheme performance is demonstrated for a convolutional code concatenated with THP on few exemplary channels. Gains of up to 10 dB are demonstrated.
