FREQUENCY HOPPING SPREAD SPECTRUM

A signal structuring technique employing automatic switching of the transmitted frequency . Selection of the frequency to be transmitted is typically made in a pseudo-random manner from a set of frequencies covering a band wider than the information bandwidth . The intended receiver would frequency- hop in synchronization with the code of the transmitter in order to retrieve the desired information.
