Available spectrum resources are becoming scarcer, while additional services are being integrated into wireless devices. Cognitive radio and multiple-antenna (MIMO) techniques can be combined to provide a solution to this dilemma. Given the currently available frequency bands and a set of bit-rate constrained services to be transmitted, the antennas can be partitioned among frequency bands and the...
Based on space-division-multiple-access scheme, this paper investigates the capacity of Gaussian vector multiple access channels (MAC) for distributed antennas communication system (DWCS). Simulations are conducted to compare the sum rate of Gaussian vector MAC between DWCS and traditional cellular system with co-located antennas. It is shown that the capacity advantages of DWCS-MAC increase with...
