Chip rate base band receiver processor which receives digital information containing symbol information

摘要

An X-Y, base-band receiver for code-division multiple accessing ("CDMA") is used at both base station and mobile station. The signal transmitted from a transmitter carries serial information symbols. Signals from all transmitters pass through a multi-path fading channel before they are received by the X-Y receiver. There is more than one instance of each symbol. The X-Y receiver searches for all instances of each symbol and combines all instances.
