Abstract: (3107 Views)
In this paper, power and sub-carrier allocation in a MIMO-OFDM based multicast system are jointly proposed to increase the system capacity. The issue of fair allocation of the resources between the multicast groups is also discussed. To achieve these goals, a sub-optimal allocation algorithm is proposed. The proposed algorithm, in addition to have a low computational complexity, allocates a certain amount of resources to all users in the multicast group. In addition, an optimal combination of the genetic and particle swarm optimization algorithms is proposed for joint sub-carrier and power allocation between the multicast groups. The simulation results show that the proposed methods increase the total system capacity compared to the previous ones.
Keywords: Heuristic algorithms, Fairness resource allocation, Multicast system, MIMO-OFDM system, Capacity.
