Abstract

To enhance the system throughput in a multiple access network, we discover that cooperative multiplexing can effectively increase the system traffic. A cooperative ALOHA multiple access (CAMA) is therefore proposed to achieve the optimal system throughput in fading channels by the tradeoff between cooperative diversity and cooperative multiplexing.
