Implementation of Frequency Shift Keying (FSK) modulation and demodulation in MATLAB with step-by-step waveform visualization and power spectral density plots
Detailed Documentation
This process implements Frequency Shift Keying (FSK) modulation and demodulation in MATLAB. The implementation begins with modulation, converting digital signals to analog signals while generating waveform plots for each processing stage. The demodulation phase then converts the analog signals back to digital format, accompanied by corresponding waveform diagrams and power spectral density plots. Through MATLAB's signal processing toolbox functions like fskmod() and fskdemod(), this demonstration provides clear insights into FSK principles and performance characteristics. The code includes key algorithmic steps such as carrier frequency generation, symbol mapping, and matched filtering operations, making it particularly useful for understanding digital communication system implementations.
