  • A novel algorithm is proposed in this literature to estimate the transmit and receive antenna correlation matrix, RT and RR, in MIMO system. Theoretical analysis indicates that the estimation performance is improved when more training number is used. Interestingly, the performance of the estimation of antenna correlation matrix at one side is highly correlated to the correlation degree of the antennas at the other side, but not the correlation degree of itself. Moreover, the relationship between estimation performance and antenna numbers is also presented. Simulation results show that mean error of this algorithm is generally below 0.05 when 200 training symbols are used.
