his paper proposes a cooperative sensing algorithm based on distributed fusion strategy and maintained probability of false alarm for cognitive radio. It further introduces a reporting strategy that discusses how cooperative sensing in distribu

Cognitive Radio false alarm

认知无线电主用户信号为BPSK信号在不同信噪比下的检测概率和虚警概率-Cognitive radio primary user signal is BPSK signals in different SNR detection probability and false alarm probability

In this paper we uate the performance of cooperative spectrum sensing (CSS) where each cognitive radio (CR) employs an improved energy detector (IED) with multiple antennas and uses selection combining (SC) for detecting the primary user (PU) in
