1. A spread spectrum receiver, comprising:

  • an antenna for receiving a composite signal;

    processing circuitry for converting the composite signal into a baseband signal;

    a sampler for sampling the baseband signal non-uniformly; and

    a sliding correlator for correlating the non-uniformly sampled baseband signal with at least one section of at least one spreading code, the sliding correlator including a delay line, a plurality of delay taps from the delay line, a plurality of multiplying taps, each multiplying tap connecting to a different one of the plurality of delay taps for multiplying a value carried by the corresponding delay tap to generate an output, and a plurality of summers, each summer summing outputs of the multiplying taps.
