WebAug 27, 2014 · 1. Spread Spectrum (SS) Spread Spectrum is a technique in which pseudonoise code, independent of the information data, is employed as a modulation waveform to spread the signal energy over a bandwidth much greater than the signal information bandwidth. Band expansion is achieved by a second modulation. The term … WebApr 24, 2024 · FHSS uses the 2.402 2.480 GHz frequency range in the ISM band. It splits the band into 79 non-overlapping channels with each channel 1 MHz wide. FHSS hops between channels at a minimum rate of 2.5 times per second. Each hop must cover at least 6 MHz. [4] FHSS uses Gaussian Frequency shift keying (GFSK) for its modulation.
