摘要

研究了多时隙协同频谱感知(CSS)的性能。多个认知无线电(CR)用户在多个感知小槽中感知主用户(PU)频谱，并使用OR规则将每个槽的决策组合起来，以评估关于PU的局部决策。所有的cr通过消褪报告通道(R-channel)向融合中心(FC)发送本地决策。FC根据多数逻辑融合规则对PU做出最终决定。从感知阈值、小槽数、感知信道信噪比(S-SNR)等不同感知参数的检测概率和漏检概率两方面研究了频谱感知的性能。

Multi-slot Spectrum Sensing in Fading Channels for a Cooperative Cognitive Radio Network

The performance of cooperative spectrum sensing (CSS) with multi-slot sensing has been investigated. A number of cognitive radio (CR) enabled users sense the primary user (PU) spectrum in multiple sensing mini-slots and the decision of each slot is combined using OR rule to evaluate the local decision about PU. All the CRs send their local decisions over faded reporting channels (R-channel) to fusion centre (FC). FC takes the final decision about PU on the basis of majority logic fusion rule. The performance of spectrum sensing has been investigated in terms of detection probability and missed detection probability for different sensing parameters such as sensing threshold, number of mini-slots and sensing channel SNR (S-SNR) etc.
