Research of Space-Time Correlation Model for Radio Systems with Diversity Transmission
Abstract
The research on MISO-systems noise-immunity of multiple diversity based on mathematical theory of diversity reception for correlated channels is presented in the article. As a result of the research, general spatial correlation coefficient is developed. Transmit signal cross-correlation coefficient based on the theory of quasiorthogonal space-time coding is developed. Channel coefficient matrix is developed using multiple-correlation coefficient that involves influence of two correlation factors. Bit error rate (BER) for MISO-system with M -diversity is estimated by error probability function based on eigenvalues of channel coefficient matrix. BER curves are calculated theoretically for several cases of MISO. MATLAB computer simulation results of BER are shown for several MISO-systems of M -diversity in order to support theoretical results.
