摘要

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