BER performance comparison of MIMO system with STBC and MRC over different fading channels
In the present wireless scenario, multiple-input and multiple-output (MIMO) is an emerging technique in wireless communication to achieve reliability and high throughput. Transmit diversity i.e. Alamouti space time block codes (STBC) and receiver diversity i.e. maximal ratio combining (MRC), are used to improve the link performance. In this paper, bit error rate (BER) performance is evaluated using distinct modulation schemes like BPSK, QPSK, and 16-QAM with STBC and MRC diversity techniques over Rayleigh, Rician and Nakagami-m fading channels. It is shown by simulated results that improved BER is achieved using MRC. Signal-to-noise ratio (SNR) is considered from 0 to 20 dB.
