Transmit Antenna Number Identification for MIMO Cognitive Radio Systems in the Presence of Alpha-Stable Noise

Identification of communication parameters, a major task intelligent receivers, has important applications in systems, especially cognitive radio systems. Multiple antennas make the identification problem more challenging. In this paper, we focus on detecting number transmit multiple-input multiple-output (MIMO) A novel algorithm is proposed to determine for MIMO systems presence alpha-stable noise. We first introduce correlation matrix based fractional lower order statistics (FLOS) and provide particular structure FLOS-based matrix. Then, eigenvalues are employed construct test statistic central limit theorem exploited obtain decision threshold. Finally, transmit-antenna detected using serial binary hypothesis test. Simulation results demonstrated evaluate effectiveness detection
