Abstract :
When TCM is used in frequency selective fading channels. A simple receiver can be used that consists of a decision-feedback equaliser, deinterleaver, and decoder. In this receiver, error propagation of the decision-feedback equaliser significantly degrades the TCM system performance. A metric calculation scheme of TCM decoder robust to error propagation in decision-feedback equalisers is proposed. Computer simulation shows the usefulness of the proposed scheme
