Cooperative Spectrum Sensing Based on Double Thresholds Energy Detection over Imperfect Reporting Channels
In this paper,the problem of hierarchical cooperative spectrum sensing using double thresholds energy detector over imperfect reporting channels will be investigated.When taking error effect on reporting decision into consideration,the sensing performance will be affected.In the proposed scheme,we analyze the performance of hierarchical cooperative spectrum sensing over imperfect reporting channels and the majority-decisionaided weighting rule will be used in the fusion center.The analysis and simulation results show that there is a significant performance loss when the decisions based on hierarchical spectrum sensing are transmitted over imperfect reporting channels and the sensing performance is improved by employing the new weighting rule.
