认知无线电中新的基于MED的频谱感知算法
A Novel Spectrum Sensing Algorithm Based on MED for Cognitive Radio
摘要
Abstract
A novel spectrum sensing algorithm based on maximum eigenvalue detection (MED) is proposed for cognitive radio.Using the recent results of the large dimensional random matrix theory (LDRMT),a new theoretical decision threshold is obtained for MED method.The new decision threshold has more reliable sensing performance and higher detection probability.Simulation results verify the effectiveness of the new MED algorithm.关键词
