ABSTRACT:
A receiver for a spread spectrum communication system is disclosed in which a transmitter transmits a data signal to a receiver includes a memory for storing digital representation of the data signal received by the receiver. A memory input addressing unit defines a circulating data window. A first ring shift register circulates a first set of components of a spreading code. A second ring shift register circulates a second set of components of a spreading code. A selector selects one of the first set of components or the second set of components as selected components of the spreading code and an adder receives as inputs digital representations of the data signal from the circulating data window and the selected components of the spreading code. The adder provides an output that is the dot product of the inputs.
