| Abstract: | In multi-user MIMO(Multiple-Input Multiple-Out put) interference channel environment,in order to fully utilize the systems total power,disruption to the user to maximize overlapping,thereby improving system performance.The MIMO interference channel model and interference subspace scheduling algorithm analysis are given;to maximize the use of system power,a dynamic power allocation algorithm for interference arrangement is presented.Simulation results show that the program is only at a small expense of system capacity,but significantly reduces the systems average error rate and interference power,to prove that the algorithm is better than the algorithm given the power advantage. |
