| Abstract: | A primary objective of this paper is to examine the achievable rate region of frequency selective K-user multiple access channels (MACs) with soft-cancelling frequency domain minimum-mean-squared-error (SC FD-MMSE) turbo equalization.With the aid of the knowledge about the extrinsic information transfer (EXIT) characteristic of the equalizer, we study the problem of determining the optimal rate allocation (RAAL) to the K users, for which the sum rate is maximized, and introduce a heuristic approach based on the dynamic programming principle for solving this optimization problem. We also propose a practical code selection algorithm for the RAAL to theK users given the multidimensional EXIT functions of the equalizer. It is shown through simulations that with SC FD-MMSE turbo equalization, substantial throughputgain can be achieved with the proposed RAAL technique over automatic repeat request with fixed coding rate. |
