D2D Physical Layer MATLAB Simulator

The D2D Physical Layer MATLAB Simulator is a specialized tool designed for research and simulation of Device-to-Device (D2D) communication systems. In various wireless network scenarios, D2D communication enables direct data exchange between terminal devices without routing through base stations, thereby improving spectrum efficiency and reducing transmission latency.

Implemented using MATLAB, this simulator models core physical layer technologies in D2D communications, including channel allocation algorithms, power control mechanisms, interference management techniques, and link adaptation strategies. The implementation typically involves functions for configuring communication parameters, simulating wireless channel conditions, and calculating performance metrics. Users can evaluate key performance indicators such as throughput, latency, and energy efficiency under different network configurations by adjusting parameter settings through MATLAB scripts or GUI interfaces.

Unlike higher-layer simulation tools, this MATLAB-based simulator focuses on physical and MAC layer details, making it suitable for investigating signal processing algorithms, resource scheduling strategies, and wireless transmission optimization schemes. The simulator likely contains modules for simulating modulation/demodulation, channel coding, and multiple access protocols. Researchers can utilize this tool to rapidly validate theoretical models and conduct feasibility analysis before actual network deployment, with the ability to extend functionality by modifying MATLAB code for specific research requirements.
