ABSTRACT:
A spread-spectrum receiver for time sharing a correlator for simultaneously receiving a plurality of parallel spread-spectrum signals. A combined multiplicity of symbols includes a multiplicity of symbols, simultaneously occurring during a symbol-time duration, from a plurality of spread-spectrum signals. A demultiplexer demultiplexes a sequence of the combined multiplicity of symbols into a plurality of symbol registers. Each of the symbol registers stores the chip-sequence signals corresponding to the combined multiplicity of symbols which were sent to the particular symbol register. A multiplexer selects a symbol register, other than the symbol register selected by the demultiplexer. The multiplicity of chip-sequence signals stored in the selected symbol register by the multiplexer are compared by a comparator with a multiplicity of replicas of the chip-sequence signals used to generate the spread-spectrum signals.
