“…The Alamouti scheme employs diversity at the transmitter whereas the MRC scheme uses diversity at the receiver. In the MRC at the receiver, the signals received through all diversity links are cophased, weighted proportionally, and then combined (Das and Subadar, 2017;Tiwari and Saini, 2014). Although the MIMO-MRC is one of the best methods for maximising the SNR, it is significantly affected by 'Co-Channel Interference (CCI)' (Kang and Alouini, 2003;Ahn et al, 2009;Tiwari and Saini, 2014).…”

“…From the above literature review and analysis, it is observed that the MRC scheme employed by Alamouti (1998) and Alqahtani et al (2019) over the AWGN channel reduces BER up to the value of 4 10  . On the other hand, over Rayleigh fading channel the MRC scheme employed by Van Luong and Ko (2018);Misra et al (2017) and Das and Subadar (2017), reduces BER in the range from 4 1 0  to 5 10  . All the above authors have used 1 2  and 1 4  or 1 6  antenna systems for the BER reduction.…”

In high-speed wireless systems, bandwidth, transmit power, the complexity of hardware, quality of services, and throughput are the major issues. The 'Multi-Input-Multi-Output (MIMO)' system specifically works to increase the capacity of the wireless channel and to improve the 'Bit-Error-Rates (BER)' performance. The 'Orthogonal-Frequency-Division-Multiplexing (OFDM)' system is used for diminishing interferences within the available bandwidth. The spatial diversity of MIMO and the spectral efficiency of OFDM schemes can be combined to improve the channel capacity and error performance remarkably within the available bandwidth. Also, this combination provides robustness against various channel impairments. This article illustrates antenna diversity by employing different antenna configurations for the improvement in ergodic channel capacity. The 'Maximal-Ratio-Combing (MRC)' scheme provides receiver antenna diversity which enhances the channel capacity and improves the error rates performance of the MIMO-OFDM-based wireless communication system. Simulation results show that the proposed schemes achieve better results for channel capacity and error-rate performance.

SummaryThis paper presents a new and exact expression for the bit error probability (BEP) of the square M‐ary quadrature amplitude modulation (M‐QAM) scheme, with the channel under double gated additive white Gaussian noise (G2AWGN) and η‐μ fading in a communication system using the spatial diversity technique. The expression for the BEP is written in terms of the Appell function. The BEP curves are presented under different values of the number of branches of the maximum ratio combining (MRC) receiver, order of the constellation M, and parameters that characterize mathematically the channel, corroborated by simulations performed with Monte Carlo method.
