Abstract

A multi-channel coordinated spectrum sensing method based on improved Genetic Algorithm is proposed to tackle low throughput issue due to inefficient signal channel serial detection in conventional cognitive radio. The proposed method detects different spatial frequency channels with multi-antenna of cognitive user synchronously. Under the limitation of target detection probability, improved Genetic Algorithm is utilized for optimization of antenna allocation to maximum throughput of cognitive channel. With fully exploiting the diversity of multi-antenna, low throughput of conventional algorithm is improved in cognitive system. The simulation shows, the proposed algorithm increases throughput of cognitive channel significantly when compared with random allocation.
