Systems and methods are provided for a correlator system. The system includes a plurality of numerically controlled oscillators and a multiplier configured to receive an input stream representing a received signal. A carrier multiplexer is configured to select between respective outputs of at least two of the plurality of numerically controlled oscillators and provide the selected output to the multiplier. A code generator is configured to provide a replica code. A delay component is configured to provide a delayed code from the replica code. A code multiplexer is configured to selectively provide each of the delayed code and the replica code to the multiplier.
