A QoS-Guaranteed Adaptive Resource Allocation Algorithm with Low Complexity in OFDMA System

摘要：

This Orthogonal Frequency Division Multiple Access (OFDMA) technique is considered. We do research on the subcarrier, bit and power allocation algorithm in it and propose the novel dynamic subcarrier and bit allocation algorithm – QoSGuaranteed Adaptive Resource Allocation Algorithm with Low Complexity for real-time services when the instantaneous channel gain is considered. Then we can derive the better system performance when the adaptive algorithm is used in the resource allocation scheme, and it can derive the lower power and complexity in contrast to other existing algorithms.
