Cognitive radio (CR) technology is an emerging technology to improve the utilization of radio spectrum. Cooperative sensing is used to enhance the efficiency of the cognitive radio network (CRN). In this paper, we consider the probability of detection or false alarm under constant detection rate and constant false alarm rate scenarios over the imperfect(More)
In this paper, we theoretically study the bit error rate (BER) performance of OFDM systems with MDPSK modulation for subchannels in frequency-selective flat Rician fading and additive white Gaussian noise (AWGN). Both the Rayleigh and Rician fading conditions are considered. The differential detection technique is used to avoid the need of a complex(More)
The research on non-cooperative multiuser multiple-input multiple-output with space-time block code (MIMO-STBC) communication systems is a challenging and important task. However, to our knowledge, there is little report of this topic. Being two key research issues in this area, modulation classification and user number detection are studied in this paper.(More)
