Optimal Throughput Analysis of Cognitive MISO System
In this paper, the authors examine a cognitive MISO system with both cognitive link and primary link communicate using multiple transmission antennas. High layer information is used to predict the idle slot existing possibility and investigate the possibility of detection errors in real circumstances. How much influence of idle slot probability and detection error will bring to stability of the cognitive interference channel is estimated. Based on the analysis, throughput analysis and power allocation schemes of two different scenarios are studied. The proposed mathematical analysis is complemented by various performance evaluation results, which demonstrates the accuracy of the theoretical approach.
