MATLAB Simulation of Frequency-Selective Channel Models Across Different Versions

In this project, we conduct MATLAB simulations of multiple implementations of frequency-selective channel models. The simulation package includes detailed Word documentation explaining the underlying principles, channel modeling techniques, and implementation methodologies to facilitate better understanding of the simulation results and approaches. During the simulation process, we employ various channel parameters and environmental conditions, utilizing MATLAB's Communications Toolbox functions such as `comm.RayleighChannel` and `comm.RicianChannel` for generating multipath fading profiles. We implement different tap-delay line configurations using the `stdchan` function to model varying delay spreads and Doppler spectra. The comparative analysis of different channel model versions involves performance metrics like Bit Error Rate (BER) calculations using `berfading` function, power delay profile analysis through `pdplot`, and coherence bandwidth evaluations. This systematic comparison provides comprehensive data insights for making accurate decisions regarding channel model optimization and selection. We perform detailed analysis of simulation results using MATLAB's visualization tools, including constellation diagrams with `scatterplot`, frequency response plots with `freqz`, and time-domain channel impulse response visualizations. The results are interpreted in context of wireless communication standards, enabling meaningful comparisons with existing research work. This project establishes a solid foundation for future research and applications by providing hands-on experience with frequency-selective channel modeling, implementing key algorithms like Jakes' model for Doppler spectrum generation, and understanding practical considerations for wireless system design under various fading conditions.
