What is frequency hopping spread spectrum technique?

Frequency-hopping spread spectrum (FHSS) is a method of transmitting radio signals by rapidly changing the carrier frequency among many distinct frequencies occupying a large spectral band.

What is spread spectrum explain it with a diagram?

Spread Spectrum refers to a system originally developed for military applications, to provide secure communications by spreading the signal over a large frequency band. Figure 1 represents a narrow band signal in the frequency domain. These narrowband signals are easily jammed by any other signal in the same band.

What is difference between frequency and spread hopping?

In the spread spectrum, the information is transmitted in short breaks of data at different carrier frequencies. In the frequency-hopping spread spectrum (FHSS), each component is transmitted at a different carrier frequency.

How FHSS achieves the goals of bandwidth spread spectrum?

"The frequency hopping spread spectrum (FHSS) technique uses M different carrier frequencies that are modulated by the source signal. At one moment, the signal modulates one carrier frequency; at the next moment, the signal modulates another carrier frequency."
