Cognitive radio is the enabling technology that allows the design of dynamic spectrum sharing algorithms that makes unlicensed users able to use frequency bands owned by license holders. Hence, this technology can be considered as the perfect candidate to enhance the spectrum allocation for the next generation of wireless networks. In this paper, we propose two low complexity heuristic algorithms...
We propose efficient scheduling algorithms for down-link MIMO-CDMA systems using zero forcing beamforming to achieve high system throughput with low computational complexity. Based on a graph theoretical approach, we propose to represent the system as a graph and to formulate the scheduling problem as the maximum weight k-colorable subgraph problem. The proposed algorithms make use of two heuristic...
