Abstract:
The patent relates to a spread spectrum link in which a transmitter section generates a different frequency signal for each unique data symbol accepted from the data source and phase shift modulates the frequency signals with a sequence of spread spectrum symbols. The frequency differences used are such that orthogonality is obtained over the receivers observation time of each spread spectrum symbol.
