FHSS vs DSSS Spread Spectrum Technologies

This document explains the principles of Direct Sequence Spread Spectrum (DSSS) and Frequency Hopping Spread Spectrum (FHSS), two spread spectrum technologies used in wireless communication. It compares their performance in different interference environments, detailing how DSSS spreads data across a broad frequency range for lower power density and redundancy, while FHSS divides the spectrum into channels and hops between them to avoid interference.
