Spread spectrum modulation techniques
WebSpread spectrum modulation techniques generate a transmission signal with a bandwidth that is much wider than the original information bandwidth. In a direct sequence spread spectrum (DSSS) communications system, the spreading of the information bits is performed by their modulation with a pseudo-noise (PN) sequence before transmission. WebSpread spectrum modulation techniques generate a transmission signal with a bandwidth that is much wider than the original information bandwidth. In a direct sequence spread …
