Abstract:
1. A method for improving a signal-to-noise ratio in a received signal, comprising: receiving, by an electronic circuit, 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; determining, by said electronic circuit, whether a magnitude of a number included within a coherent time synchronized copy of said series of random numbers which was used to generate said spread spectrum signal exceeds an adaptable threshold value; selectively excluding, by said electronic circuit, a respective sample of said received spread spectrum signal from a receiver processing step if it is determined that said number does not exceed said adaptable threshold value; and selectively forwarding, by said electronic circuit, said number and said respective sample to a correlation device or a de-spreading device if said magnitude of said number was determined to exceed said adaptable threshold value.
