Deliberately spread a signal over far more bandwidth than it needs

Spread spectrum is a transmission approach that deliberately spreads a signal across a bandwidth much wider than the information rate requires, using a spreading code known to the receiver, so the signal becomes resistant to narrowband interference and jamming, hard to intercept, and able to share a band with others. Scholtz's 1982 The origins of spread-spectrum communications traces the technique's development from wartime secure communications and ranging. The referent is the intentional bandwidth-spreading of a signal for robustness and multiple access, realised as direct-sequence or frequency-hopping and underlying CDMA, GPS, and many wireless standards.[1]

Unit
The ratio of occupied bandwidth to information bandwidth (processing gain)
Recovery means
Not applicable
Measured by
Quantified by processing gain, jamming margin, and interference rejection relative to a narrowband signal
