Technical Guideline for Time and Frequency Diversity in OFDM Systems Under Rician Fading: MATLAB Simulation Framework

This paper presents a practical guideline to implement and evaluate time and frequency diversity techniques in Orthogonal Frequency Division Multiplexing (OFDM) systems under Rician fading using MATLAB R2024a. The MATLAB framework allows flexible configuration for several parameters, such as modulation schemes, cyclic prefix lengths, and channel parameters. We present the results in terms of Bit Error Rate (BER) versus Signal-to-Noise Ratio (SNR) and Power Spectral Density (PSD). Our software aims to facilitate the study of different diversity techniques in OFDM systems for both academics and students.
