Frequency Hopping System Simulation Module with OFDM Modulation

This simulation module implements a frequency hopping system using Orthogonal Frequency Division Multiplexing (OFDM) modulation, built with Simulink toolbox. The system allows dynamic configuration of key parameters including hopping rate, number of frequency hops, carrier frequency, hopping interval, FFT operation length, and cyclic prefix length. Channel models support both Rayleigh multipath fading and Gaussian channels with customizable parameters. The implementation utilizes Simulink's DSP and Communications toolboxes for signal processing blocks and OFDM modulation/demodulation components.

Simulink Toolbox Simulation

Simulation using MATLAB's Simulink toolbox. Implements a single-phase bridge PWM inverter circuit with unipolar triggering method. Models the load and power supply, creates a PWM triggering module, and plots the relationship between fundamental wave amplitude and duty cycle.
