1. A method for improving a signal-to-noise ratio in a received signal, comprising:

  • receiving a spread spectrum signal which has been generated by modulating a data signal using a spreading sequence comprised of a series of random numbers, said spreading sequence having a higher rate as compared to said data signal;

    comparing a magnitude of each number comprising a coherent time synchronized copy of said series of random numbers which was used to generate said spread spectrum signal to an adaptable threshold value; and

    selectively excluding samples of said received spread spectrum signal from a receiver processing step based on a result of said comparing step.
