Performance Analysis of Millimeter-Wave Based Device-to-Device Communications System

Millimeter-wave (mmWave) communication has emerged as one of the critical technologies in the fifth-generation (5G) wireless system by providing resources to overcome the ever-increasing demand for high data rates and low latency. Utilization of directional mmWave for device to device (D2D) communication systems provide low powered, high data rate transmission with manageable interference. In this paper, an analytical mathematical framework is proposed for a system wherein mmWave technology is incorporated in D2D communication. The proposed model consists of a base station (BS), a cellular user (CU), and other nodes that are communicating via mmWaves. The interference links can be in line of sight (LOS) or non line of sight (NLOS). Closed-form expressions for signal-to-interference-plus-noise ratio (SINR) and outage probability are devised and verified using simulations with different system parameters. A comparative study of all possible LOS and NLOS communication link setups reveals that outage probability is minimum if the interfering links are in NLOS.
