SCFDMA Simulation Code Implementation on MATLAB Platform

This article presents simulation code for Single-Carrier Frequency Division Multiple Access (SCFDMA) implemented on the MATLAB simulation platform. First, we provide a detailed explanation of SCFDMA technology and its practical applications in modern communication systems. Subsequently, we conduct an in-depth analysis of SCFDMA principles and system models, explaining implementation approaches in MATLAB using digital signal processing techniques and communication toolbox functions. Building upon this foundation, we systematically demonstrate the simulation code development process, covering critical aspects such as parameter configuration (including sampling rates, carrier frequencies, and modulation schemes), data processing workflows, and key algorithm implementations like DFT-spreading and subcarrier mapping. The implementation utilizes MATLAB's FFT functions for frequency domain processing and includes error detection mechanisms. Finally, we present several simulation experiment examples with performance metrics (BER, PAPR analysis) to help readers better understand and apply the simulation code discussed in this article. Through studying this material, readers will acquire comprehensive skills in developing and applying SCFDMA simulation code on the MATLAB platform, including optimization techniques for real-time processing scenarios.
