Abstract

In this paper to improve both bandwidth efficiency and error performance, partial response signalling (PRS) and trellis coded modulation (TCM) are combined together and denoted as Modified/Quadrature Partial Response-Trellis Coded Modulation (M/QPR-TCM) for M-PSK. M/6QPR-TCM, M/9QPR-TCM and M/33QPR-TCM schemes are introduced for 4-PSK and 8-PSK respectively. In colored noise environment for negative noise correlation coefficient values M/QPR-TCM schemes outperform better than the classical structures. In fading channels, the proposed schemes are better than their counterparts for SNR values greater than a threshold. In terms of spectral efficiency and bit error rate with decreasing fading parameter K values, M/QPR-TCM systems appear to be the best choice in the literature
