Abstract

Device-to-Device (D2D) communications is a term used to describe the technology that allows two devices to communicate with each other directly without using the Base Transceiver Station (BTS) or indirectly with the BTS. Device-to-device (D2D) communication plays a very significant role in the traditional cellular networks as it promises ultra-low latency for communication among users. Device-to-Device emerged as the key technology advances in mobile wireless communications. This paper analysed the performance metrics, using Multiple Input Multiple Output (MIMO) techniques for enhancing signal transmission in (D2D) communication. The system parameters Signal-to-Noise Ratio (SNR), Interference-to-Signal Ratio (ISR), Received Signal Strength Indicator (RSSI), distance and Capacity were analysed; using MIMO technique and comparing the signal flow across the different signal interference and probation delay. MATLAB/SIMULINK is used in simulating the different parameters in comparing the performances of the network. The MIMO technique enhances to a greater degree the signal propagation and path strength improvement over other traditional systems techniques, as a result of multi-path signal navigation improves signal reliability across paths with better fidelity. In the simulation results, increasing the number of antennas at the transmitter and the receiver end gave spatial diversity gain. Which results in a simultaneous increase in signal strength at the transmitter and receiver with a decrease in communicated interference.
