Research Abstract

Abstract—This work proposes a reduced complexity secure cooperative cognitive radio spectrum sensing algorithm for wideband systems. The main goal of the proposed algorithm is to reduce the cognitive radio receiver hardware complexity by distributing the sensing work among the trustful nodes only. Each cognitive radio node uses its local sensing matrix, which is a part of a global sensing matrix at the fusion center, to sense the wideband analog signal. The fusion center selects and rearranges the compressed data from the trustful ...
