In this paper, we consider a device-to-device (D2D) cellular communication network where the wireless communication link among the devices and the base stations (BS), and between two devices is subjected to Rician fading and Nakagami-m fading distributions, respectively. The BSs and the devices are assumed to be placed randomly as independent Poisson point processes with the typical cellular user experiencing interference from both the D2D users and the BSs. We have investigated two scenarios, firstly both the BSs and the D2D users transmit orthogonal frequency division multiplexing with cyclic prefix (CP-OFDM) symbols for data transmission, and secondly, the BSs transmit CP-OFDM symbols while the D2D users transmit orthogonal quadrature amplitude (OQAM) modulated symbols over a filter bank based multi carrier (FBMC) transmitter system. Using the techniques of stochastic geometry, series form expression of the coverage probability of the cellular users is derived for the underlying interference-limited D2D cellular network. Moreover, the optimal coverage values that maximize the energy efficiency of the network are also obtained analytically. The study of the performance metrics obtained by numerical results provides insights on the dependence of the type of interference from the D2D users and of the type of modulation to be employed at the D2D users on the performance of the system.
