摘要

为了提高QAM的带宽效率和误差性能，本文将部分响应信号和栅格编码调制相结合。研究了一种采用组合部分响应码调制(QPR-TCM)的新型数据传输接收机。因此，引入了6QPR-TCM和42QPR-TCM组合系统。在IS1环境下进行了仿真研究。在有色噪声环境下，与经典的4QAMTCM相比，6QPR-TCM的误差概率是解析下界的。

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

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 .
