Reduced-Decoding Complexity Of Quadrature Partial Response Trellis Coded Modulation (QPR-TCM) In The Presence Of Intersymbol Interference

Abstract

In this paper, to improve both bandwidth efficiency and error performance, partial response signalling and trellis coded modulation are considered together for QAM. A new receiver for data transmission systems employing combined partial responsetrellis coded modulation (QPR-TCM) i s investigated. Thus, combined 6QPR-TCM and 42QPR-TCM systems are introduced. Simulation studies in IS1 environment are done. In colored noise environment, the error probability of 6QPR-TCM is analytically lower bounded and compared to the classical 4QAMTCM .
