Diversity gain provides the number of independent paths between the transmitter and the receiver. Asymptotic outage probability expression is derived at A 8 as [14] 6 Energy Harvested Device-to-Device MIMO Systems for Beyond 5G (6.31) Ns-1a(Msr-1) [1+a(1- (6.32) NR-1q(MRD-1) [1+p(1-PRD)] (6.33) [1+e(1- (6.34) where diversity order is given by d1, d2, and d3. Further, M = MSR = MRD, d1 = MSD + MSR, d2 = MSD + MRD, and d3 = MSD + M. Furthermore, ksd = AsD 6.4.2.3 Throughput Analysis We consider a delay-limited transmission mode for the analysis of throughput. Thus, in this mode throughput is evaluated for a fixed transmission rate Rr = log2(1) + Ae2e) bits/s/Hz from the outage probability as (6.35) 6.4.3 Results and Discussions In this section, we discuss the derived analytical expressions from the various system design aspects and validate them through the Monte Carlo simulations. The system modeling parameters are considered as follows: correlation parameters (CPs) as {PSR, PRD, PSD}, transmission rate Rr = 3 bits/s/Hz, and EH efficiency factor (n = 1). In the analysis, urban macro-cell network environment is considered with path loss exponent 4 [39]. P. Shaik and V.

In the analysis, EH is performed for a = 0.2T, and CPs are taken as {0.9, 0.9, 0.9}. The derived analytical UB results match well with the asymptotic results, and Monte Carlo results validate them. Curves illustrate that for an outage probability of 10-5
