Spread spectrum communication system implementation including direct sequence spread spectrum, PN sequence generation, and frequency hopping spread spectrum with MATLAB code examples

MATLAB Implementation of Frequency Modulation Spread Spectrum

Frequency Modulation Spread Spectrum (FM-SS) and Differential Frequency Hopping (DFH) represent emerging spread spectrum communication technologies that integrate frequency hopping patterns, information modulation, and demodulation functionalities into a unified framework. This creates a fundamentally different technical architecture compared to traditional frequency hopping systems. This article provides a comprehensive introduction to DFH technology, analyzing its core technical components while highlighting both advantages and unresolved challenges in practical implementation through MATLAB code examples.
