Description
Summary:In this paper, we present a new bandwidth-efficient coded modulation scheme based on parallel concatenation of the three component trellis coded modulation (TCM) encoders. The resulting triple parallel concatenated TCM (TPCTCM) is investigated for the spectral efficiency of 2 to 7 bits/sec/Hz based on two-dimensional (2-D) TCM employing PSK and QAM signal sets. The component code is designed based on the symbol-based three-dimensional (3-D) extrinsic information transfer (EXIT) charts. The simulation results in terms of frame error rate (FER) performance demonstrate that the proposed TPCTCM can significantly reduce the error floor of the conventional parallel concatenated TCM.
