Achieving general points in the 2-user Gaussian MAC without time-sharing or rate-splitting by means of iterative coding

Achieving general points in the 2-user Gaussian MAC without time-sharing or rate-splitting by means of iterative coding

In this paper, we analyze iterative coding for the frame-asynchronous binary-input discrete-time Gaussian multiple access channel. Using the method of density evolution, we optimize degree distributions to exhibit code ensembles whose iterative decoding thresholds are only few tenths of dB away from...

Zusammenfassung:In this paper, we analyze iterative coding for the frame-asynchronous binary-input discrete-time Gaussian multiple access channel. Using the method of density evolution, we optimize degree distributions to exhibit code ensembles whose iterative decoding thresholds are only few tenths of dB away from the Shannon limit.
