“…Further, inband communication is classified into the underlay and overlay D2D communication. In the underlay D2D communication, cellular user equipments (CUEs) and device user equipments (DUEs) share the same spectrum by keeping the interference below a predefined threshold [7]. In overlay D2D communication, CUEs and DUEs are given with dedicated spectrum to avoid interference [8].…”

“…Further, exact and asymptotic average bit error rate expressions for the BPSK scheme is obtained. In [7], authors have obtained the outage probability, asymptotic outage probability, and ergodic sum rate for a two-way MIMO D2D overlay communications. In [21], ASER of SQAM scheme is evaluated for orthogonal frequency division multiplexing (OFDM) based multiple relay system with a non-linear power amplifier over Nakagami-m fading channels.…”

In this paper, we investigate the performance of a device-to-device (D2D) multiple-input and multiple-output (MIMO) communications using an amplify-and-forward relaying for various energy-efficient modulation schemes. For analysis, transmit antenna selection strategy is employed at the transmitter to select the best transmit antenna which maximizes the received signal power. In the analysis, we optimized the relay location to obtain the lowest outage probability possible and derived the generalized upper-bound average symbol error rate expressions of energy-efficient futuristic modulation schemes such as square quadrature amplitude modulation (QAM), rectangular QAM, cross QAM, and hexagonal QAM for D2D network. Further, we have derived the ergodic capacity expression to calculate the achievable rates. Comparative analysis of different QAM schemes for various constellation orders is also presented. Furthermore, the impact of the relative position of relay, path loss, and the number of antennas are also highlighted. Finally, the derived analytical results are verified through Monte-Carlo simulations.

In this paper, we propose and investigate a three‐phase overlay spectrum‐sharing scheme for device‐to‐device (D2D) communications in a bidirectional cellular network with nodes mobility. In this scheme, a pair of D2D users facilitates relaying to the cellular nodes (base station and mobile user), and in return, they get the opportunity to exchange their own information by exploiting the same cellular spectrum. With this, the two end‐to‐end bidirectional communications (D2D and cellular) can be realized in three time phases by using selection‐combining technique at both cellular nodes and decode‐and‐forward (DF) relaying scheme at both participating D2D users. For DF operation, we consider two strategies, namely, exclusive‐OR (XOR)‐based DF, and superposition‐based DF. All the channels are assumed to be time varying, and Markovian model is used to characterize the impact of nodes mobility. For this set‐up, we first derive the outage probability for both cellular and D2D links under Rayleigh fading. Then, we obtain the asymptotic expressions of outage probability for both systems and used them further to reveal the critical value of power‐splitting factor for spectrum sharing. Above all, we acquire the expression of average system throughput to perform a fair performance comparison with the other existing schemes.
