Rate Adaptive Based Resource Allocation with Proportional Fairness Constraints in OFDMA Systems

Rate Adaptive Based Resource Allocation with Proportional Fairness Constraints in OFDMA Systems

Orthogonal frequency division multiple access (OFDMA), which is widely used in the wireless sensor networks, allows different users to obtain different subcarriers according to their subchannel gains. Therefore, how to assign subcarriers and power to different users to achieve a high system sum rate...
