Coded Modulation Assisted Iterative Parallel Interference Cancellation Aided CDMA
Coded Modulation Assisted Iterative Parallel Interference Cancellation Aided CDMA
In this contribution we investigate Trellis Coded Modulation (TCM) and Turbo Trellis Coded Modulation (TTCM) assisted iterative parallel interference cancellation aided CDMA schemes. The symbol-based Maximum~a~Posteriori (MAP) algorithm is invoked in both the TTCM and TCM decoder. In the context of the 8PSK TCM/TTCM CDMA schemes typically two iterations are necessary for approaching the best possible performance attained with the aid of an infinite number of iterations. By contrast, the number of iterations has to be increased to three or four in conjunction with 16QAM when the effective information throughput is increased from 2 to 3 bits per symbol.

Abstract
In this contribution we investigate Trellis Coded Modulation (TCM) and Turbo Trellis Coded Modulation (TTCM) assisted iterative parallel interference cancellation aided CDMA schemes. The symbol-based Maximum~a~Posteriori (MAP) algorithm is invoked in both the TTCM and TCM decoder. In the context of the 8PSK TCM/TTCM CDMA schemes typically two iterations are necessary for approaching the best possible performance attained with the aid of an infinite number of iterations. By contrast, the number of iterations has to be increased to three or four in conjunction with 16QAM when the effective information throughput is increased from 2 to 3 bits per symbol.
