Cooperative Spectrum Sensing by Sequential Change Detection in Cognitive Radio
نویسنده
چکیده
This paper proposes the solution for Spectrum Sensing Problems in Cognitive Radio Networks. For this an Adaptive CUSUM based Test for signal Change Detection algorithm is used. The algorithm is based on sequential change detection techniques which is particularly effective when the parameters are not available apriori or when the correct parameter configuration and the pdf of the signal under test are unknown. This work provides an extension of the CUSUM algorithm which allows the test parameters to be configured. The proposed Adaptive CUSUM provides accuracy, change detection readiness and computational complexity.
