摘要
Abstract
This paper focused on a resource allocation algorithm for OFDM-based cognitive radio with consideration of the influence of frequency sensing error, which applies better to practical application. The proposed resource allocation algorithm works out an energy efifcient resolution of the problem under the limitation of total power and interference. Moreover, the algorithm can satisfy minimum transmit rate requirements of all SUs. The simulation results show that the proposed algorithm reduces the computational complexity, and ensures fairness among all SUs. Meanwhile, the consideration of sensing error makes the resolution more closed to practical condition, so the algorithm can apply to real time application well.关键词
