Spread spectrum communication with white Gaussian noise
Abstract
The interchannel interference noise encountered in Spread Spectrum Multiple Access (SSMA) systems is an important determinant of the possible number of SSMA system characteristics, when white Gaussian noise is used for the spreading signal. The ratio of signal to interchannel interference noise obtained can be the theoretical upper bound for direct sequence SSMA systems. A novel SSMA system is proposed in which the delayed white Gaussian noise and the spread information signal are transmitted together, posing no synchronization difficulties between the spreading and despreading signals and allowing a considerable simplification of receiver structure.
