“…It was also mentioned that the proposed scheme may be useful for base station (BS) to BS communication. In the literature, some more works employ differential/nondifferential orthogonal/non-orthogonal space-time block code (STBC) on the subject of fastly varying channels for arbitrarily correlated Rayleigh/Ricean channels have been presented in [29,30]. On the other hand, a precoder design for orthogonal/non-orthogonal STBC over correlated Ricean MIMO channels with invertible correlation matrices has been developed in [31].…”

This paper considers the problem of massive multiple-input-multiple-output (MIMO) wireless communication systems with quasi-orthogonal space-time block code (QOSTBC) transmission in the presence of spatial correlation effect (SCE) and mutual coupling effect (MCE). Conventional MIMO channels with QOSTBC transmission suffer from several drawbacks. The number of transmit antennas is restricted to a few in order to achieve full transmission rate. Therefore, it is difficult to make a quasi-orthogonal space time block coded massive MIMO system to achieve full transmission rate. Moreover, MIMO channel with QOSTBC transmission is usually considered for the case where the number of user equipments (UEs) is one. We present a joint beamforming and spatial precoding method to deal with the above drawbacks. The proposed method incorporates a beamforming scheme and spatial precoding to formulate an appropriate optimization process to effectively alleviate the considered problems. The resulting optimization problem will be solved by using a cooperative coevolutionary particle swarm optimization algorithm under two proposed fitness functions. During the optimization process, the proposed method finds the optimal beamforming coefficients of the precoding matrix, the optimal normalized positions of transmit and receive antenna elements for the case of using linear antenna arrays, and the optimal angle differences of transmit and receive antenna elements for the case of using circular arrays. Based on the proposed method, we are able to cure the performance degradation of a quasi-orthogonal space time block coded massive MIMO system due to the SCE and MCE. Moreover, the proposed method makes QOSTBC MIMO communications with full transmission rate for any number of transmit antennas achievable. Several simulation examples are presented to show the superior bit error rate (BER) performances of QOSTBC wireless MIMO scenarios with linear as well as circular antenna arrays by using the proposed method as compared to the existing methods.

Cooperative diversity system improves the communication reliability and throughput in a multipath fading environment with the help of relay nodes. We consider a cooperative diversity system with a source (S), a decode and forward (DF) relay (R), and a selection combining (SC) enabled destination (D). In this paper, we derive the exact end-to-end symbol error probability (SEP) for M -ary phase-shift keying (MPSK) signaling using paired error approach and differential binary phase-shift keying (DBPSK) signaling over correlated, non-identical, slow, and flat Nakagami-m fading channels by assuming the correlation between SD-RD, SR-SD, and SR-RD fading channels. In addition, we perform the exact outage probability analysis for the same scenario. Further, we provide the asymptotic expressions for SEP and outage probability by removing the infinite series terms to investigate the diversity order. In a nutshell, the numerical results reveal that the SR-RD correlated channel scenario outperforms the uncorrelated channel scenario in terms of SEP. In addition, SEP performance degradation is observed in the case of other correlated channel scenarios compared to uncorrelated channel scenario. Moreover, marginal performance improvement in outage probability is observed at the low signal-to-noise ratio (SNR) regime of the SR-RD correlated channel scenario compared to the uncorrelated channel scenario. Finally, Monte Carlo simulations are performed to validate the theoretical results.Index Terms-Decode and forward (DF), differential binary phase-shift keying (DBPSK), M -ary phase-shift keying (MPSK), Nakagami-m fading, outage probability, paired error approach, symbol error probability (SEP).

“…Based on a Kronecker channel model, the precoder is designed for space-time coded MIMO (STC-MIMO) systems over joint transmit-receive correlated Rayleigh channel in [28,29] of which the mean feedback is not taken into consideration, but the precoding schemes need numerical search and iterative calculation. The study is extended to STC-MIMO systems over Rician MIMO channels with arbitrary correlation model in [30,31], where SER criteria are considered. The scheme in [31] can avoid the need for exact channel information at the transmitter due to the use of differential STBC.…”

In this paper, power adaptation strategies for minimizing bit error rate (BER) subject to an average power constraint for orthogonal space-time coded multiple-input multipleoutput (MIMO) systems with mean and covariance feedback over joint transmit-receive correlated channels are presented. We first develop an optimal spatial-only power control (PC) based on an approximated BER bound, which can include the mean feedback only and covariance feedback only as special cases. Using a newly defined fuzzy signal-to-noise ratio (FSNR) criterion, a suboptimal spatial PC scheme with a closed-form expression is derived. This FSNR-based power adaptation not only has the computational complexity less than but also obtain the BER performance close to that of the optimal spatial-only PC scheme. Second, the degrees of freedom in temporal and spatial domains are exploited to derive a joint spatio-temporal PC with the use of FSNR strategy to minimize the average BER subject to a long term average power constraint with mean and covariance feedback. Simulation results show that the proposed two spatial-only PC schemes can provide BER lower than that of the equal power allocation, and obtain almost the same performance as the existing spatial-only optimal scheme but have lower computational complexity. Moreover, they outperform the PC schemes with mean or covariance feedback only. Most importantly, the new joint spatio-temporal PC scheme substantially outperforms all the spatial-only PC schemes.
