— We use the idea of dependence balance [1] to obtain the first improvement over the cut-set bound for the discrete memoryless multiple access channel with noiseless feedback (M...
— For a three user Gaussian multiple access channel (MAC), we propose a new superposition block Markov encoding based cooperation scheme. Our scheme allows the three users to sim...
Abstract— We derive a lower bound on the diversitymultiplexing tradeoff for multiple antenna multiple access channels using temporal power control (PC). We quantify the substanti...
— This paper investigates the effect of non-zero SNR margin and coding gap on the maximum sum rate and achievable rate region of the Gaussian Multiple-Access Channel (MAC). Frequ...
Abstract— For multi-user orthogonal frequency division multiplexing (OFDM) systems, efficient optimal rate and power allocation algorithms are presented via geometric programmin...
