“…Generalization of composite multipath shadowing model can also be obtained from the product of two fading variables [6]. The effect of both shadowing and correlation was analyzed over a D-MIMO Rician/Gamma fading channel in [7], where the authors numerically analyzed how they can affect the achievable sum rate (ASR), symbol error ratio (SER), and outage probability (OP) of the system. The effect of correlation and shadowing can be overcome by diversity techniques, such as maximal ratio combining (MRC) and selection combining (SC).…”

In this era of 5G technology, the ever-increasing demands for high data rates lead researchers to develop hybrid satellite-terrestrial (HST) networks as a substitution to the conventional cellular terrestrial systems. Since an HST network suffers from a masking effect which can be mitigated by adopting the terrestrial relaying strategy, in this work, wireless multicasting is focused on through an HST relaying network (HSTRN) in which a satellite sends messages to multiple terrestrial nodes via multiple relays under the wiretapping efforts of multiple eavesdroppers. The concern is to protect the multicast messages from being eavesdropped taking advantage of the well-known opportunistic relaying technique. It is considered that the satellite links follow Shadowed Rician fading whereas the terrestrial links undergo 𝛼 − 𝜇 fading. The secrecy performance of the proposed HSTRN model is accomplished by deriving expressions for the probability of nonzero secrecy multicast capacity, ergodic secrecy multicast capacity, and secure outage probability for multicasting in closed-form. Capitalizing on the derived expressions, the authors analyze how a perfect secrecy level can be preserved in spite of harsh channel conditions and also present a secrecy trade-off in terms of the number of relays, multicast users, and multiple eavesdroppers. Finally, the numerical analyses are corroborated via Monte-Carlo simulations.

“…Rician fading has found applications even in recent times in the study of the performance of distributed multiple input multiple output (MIMO) with zero forcing (ZF) receivers over correlated Rician fading channels [14], in deriving expressions for achievable rates of MIMO relay systems with ZF processing over Rician fading systems [15] and in the study of the performance of co-operative relaying systems with non-orthogonal multiple access [16]. Existing 4G and emerging 5G systems are both interference-limited.…”

Approximate Symbol error rate (SER), outage probability and rate expressions are derived for receive diversity system employing optimum combining when both the desired and the interfering signals are subjected to Rician fading, for the cases of a) equal power uncorrelated interferers b) unequal power interferers c) interferer correlation. The derived expressions are applicable for an arbitrary number of receive antennas and interferers and for any quadrature amplitude modulation (QAM) constellation. Furthermore, we derive a simple closed form expression for SER in the interference-limited regime, for the special case of Rayleigh faded interferers. A close match is observed between the SER, outage probability and rate results obtained through the derived analytical expressions and the ones obtained from Monte-Carlo simulations.

Massive multiple-input and multiple-output (MIMO) has been recognized as a promising technology in the fifth-generation wireless networks. Under perfect channel state information, we derive three tractable closed-form expressions that corresponding to the lower bound, approximation, and upper bound on the achievable rate in a massive MIMO downlink system with maximum-ratio transmission precoding. Based on the proposed closed-form expressions, the power efficiency of the system is investigated as the number of transmit antennas increases. Simulation results demonstrate the tightness of our proposed closed-form expressions for the achievable sum-rate.
