TCM, TTCM, BICM and BICM-ID Assisted Joint Detection Based CDMA
In this contribution we studied the performance of Trellis Coded Modulation (TCM), Turbo Trellis Coded Modulation (TTCM), Bit-Interleaved Coded Modulation (BICM) and Iterative Decoding assisted BICM (BICM-ID) schemes applied in a Code-Division Multiple Access (CDMA) system in the context of 8-level Phase Shift Keying (8PSK) and 16-level Quadrature Amplitude Modulation (16QAM) for transmissions over dispersive Rayleigh fading channels. A Minimum Mean Square Error based Decision Feedback Equalizer (JD-MMSE-DFE) was utilised for multiuser detection and for mitigating the effects of both intersymbol interference as well as that of the multiuser access interference in the system. It was found that TCM is the best scheme when using a short interleaver, while TTCM is best scheme when using long interleaver, compared to the other investigated schemes at the same decoding complexity.

Abstract

In this contribution we studied the performance of Trellis Coded Modulation (TCM), Turbo Trellis Coded Modulation (TTCM), Bit-Interleaved Coded Modulation (BICM) and Iterative Decoding assisted BICM (BICM-ID) schemes applied in a Code-Division Multiple Access (CDMA) system in the context of 8-level Phase Shift Keying (8PSK) and 16-level Quadrature Amplitude Modulation (16QAM) for transmissions over dispersive Rayleigh fading channels. A Minimum Mean Square Error based Decision Feedback Equalizer (JD-MMSE-DFE) was utilised for multiuser detection and for mitigating the effects of both intersymbol interference as well as that of the multiuser access interference in the system. It was found that TCM is the best scheme when using a short interleaver, while TTCM is best scheme when using long interleaver, compared to the other investigated schemes at the same decoding complexity.
