Spread spectrum definition

Spread spectrum. (5) means the technique whereby energy in a relatively narrow-band communication channel is spread over a much wider energy spectrum.

Spread spectrum means a modulation technique used in wireless systems employing direct sequence, frequency hopping or a hybrid of these, which can be used for multiple access, multiple functions or both multiple access and multiple functions;

Spread spectrum means a form of wireless communications in which the frequency of the transmitted signal is deliberately varied, resulting in a much greater bandwidth than the signal would have if its frequency were not varied;
