WebThere are four techniques of spread spectrum namely direct sequence spread spectrum (DSSS), frequency hopping spread spectrum (FHSS), chirp spread spectrum (CSSS) and time hopping spread spectrum (THSS). Each of these techniques is described, with a brief mention about its basic mechanism.A brief comparison is drawn between FHSS AND … WebThe Frequency Hopping Spread Spectrum or FHSS allows us to utilize bandwidth properly and maximum. In this technique, the whole available bandwidth is divided into many channels and spread between channels, arranged continuously. The frequency slots are selected randomly, and frequency signals are transmitted according to their occupancy.
