A Cross-Layer Adaptive Resource Allocation Algorithm Based on Impartiality of Wait Time

摘要：

A cross-layer adaptive resource allocation algorithm of multi-user MIMO OFDM systems is proposed and simulated. The aim is to maximize the transmit rate under the constraints of the fixed transmit power and QoS. The algorithm exploits the fair of wait time of each user to allocate subcarriers whose allocation standard is the spatial subchannel whose SNR is best,bits and power of subcarriers and spatial subchannels.Simulation results show that the algorithm can satisfy the fair of wait time and QoS of each user,and the total rate can be increased significantly.
