摘要
Abstract
Aiming at the problem of spectrum detection in cognitive radio systems, this paper proposes a coordination communication reporting scheme combined with Alamouti coding and Time Division Multiple Access(TDMA), and does the detection performance analysis. The probability formulae of false alarm, missed detection and the minimum probability of false alarm are derived. Analysis results show that, as the quality of local user channel gets better, Symbol Error Rate(SER) of reporting channel decreases with a coding gain more than 3 dB, and the minimum probability of false alarm decreases obviously.关键词
