In this work we have studied the performance analysis of OSTBC-encoded 16-QAM by transmitting digital image over fading channels.The performance of 2×2 MIMO fading channels is compared with SISO fading channel with no OSTBC encoding at signal-to-noise ratio (SNR) of 20 dB. Multipath MIMO channels under-discussion are time-selective in nature and have flat channel response in frequency. Hence, we specify only Doppler shift which in our case is modelled by Jakes Doppler spectrum. The performance of 2×2 communication system over MIMO time-selective fading channels has been studied. The key performance indicative parameters of OSTBC-encoded 16-QAM over 1×1 single-input single-output (SISO), 2×1 multiple-input single-output (MISO) and 2×2 MIMO wireless communication have been recorded appropriately.
