MATLAB Implementation for Generating FSK Signals with Digital Modulation Analysis

This paper provides an in-depth exploration and analysis of methods for generating Frequency Shift Keying (FSK), Binary Phase Shift Keying (BPSK), and Quadrature Phase Shift Keying (QPSK) signals. The implementation typically involves defining modulation parameters such as carrier frequency, symbol rate, and sampling frequency, followed by mathematical modulation operations using MATLAB's signal processing functions. Additionally, we investigate computational approaches for cyclic mean, cyclic autocorrelation, and cyclic spectral density analysis. These cyclostationary signal processing techniques can be implemented using algorithms that leverage Fourier transforms and statistical moment calculations to detect periodic patterns in modulated signals. Through comprehensive study of these concepts, we can enhance understanding of digital modulation techniques and expand applications in communication system analysis and signal processing domains.
