WebQ uite simply, spread spectrum is a coding technique for digital transmission. It was originally developed for the military under a veil of secrecy. The purpose of coding is to transform an information signal so that it looks more like noise. Noise has a flat uniform spectrum with no coherent peaks and can be reduced or eliminated by filtering. http://www.airlinx.com/index.cfm/id/10-33.htm

WebSpread-spectrum communication systems spread the transmission signal over a wide frequency band, typically much wider than the minimum bandwidth required to transmit the data. The spreading uses a waveform that appears random to anyone except the intended receiver of the transmitted signal.
