Feed forward spread spectrum signal processor

Abstract From the Canadian patent

A communications receiver for a code division multiple access (CDMA) satellite communication system in which a plurality of data carriers share the same band. A pilot carrier transmits a timing reference used by all receivers to acquire the clock used in timing the code generators and used as a frequency and phase reference for data detection. This receiver employs a digital signal processor that detects a spread pilot carrier and uses the phase noise on the pilot carrier to subtract the communication link phase noise from the data carriers thus allowing communication at, lower signal-to-noise ratios.
