Error analysis of multiple rate space-time-block-code (STBC) for MIMO networks

This paper presents error performance analysis of multiple rate space-time-block code (STBC) for MIMO wireless network over Ricean fading channel. The design aspect of wireless system aims at improvement in spectral efficiency and coverage area with reliable performance. This necessitates that the MIMO system must be capable to overcome data rate limitation and there must have options open for future improvement. Error performance and spectral efficiency can further be improved by incorporating STBC with MIMO system. Recently many researchers have been working on MIMO systems with STBC to improve the performance of system without additional bandwidth or transmit power requirements. We have considered here the STBC schemes in Ricean fading environment using various combinations of numbers of transmit and receive antennas. The simulations results have been obtained in MATLAB platform. The bit error rate performance has been analyzed for the Ricean factors of k = 0,1, and 10 in 16 QAM modulation schemes.
