1. A receiving system comprising:

  • a receiver that is configured to receive a composite signal from a plurality of transmitters, each transmitter providing a transmitted signal at a different code-phase of a plurality of code-phases of a spreading code, a down-converter that is configured to provide a baseband signal from the composite signal, and a phase detector that is configured to identify the code-phase corresponding to each transmitter of the plurality of transmitters, wherein the phase detector is configured to identify the plurality of code-phases by applying a plurality of samples of the baseband signal to a Fast M-Series transform that is configured based on the spreading code.
