Abstract

Abstract:

By analyzing the multi-hop cooperative cognitive diversity network in underlay sharing(US) mode, an approximate outage probability formulation and diversity order is derived for decode-and-forward(DF) protocol in high signal-to-noise ratio to get theory equations of cognitive transport performance. A good outage performance of cognitive system with the increase of hop number in high signal-to-noise ratio is obtained. Simulation shows that multi-hop DF cooperative cognitive diversity system achieves no more space diversity gain.

Key words: cognitive radio, outage probability, space diversity, diversity gain
