1. A method for receiving transmitted signals in a CDMA communication system having a detection threshold for comparing with a sample of a received signal in order to determine the presence of CW interference in the received signal, comprising the steps of:

  • (a) obtaining a first sample of the received signal at a first sample time, the first sample including a calculated correlation value between a first input signal and a locally-generated pseudorandom code;

    (b) obtaining a second sample of the received signal at a second sample time, the second sample including a calculated correlation value between a second input signal and a locally-generated pseudorandom code;

    (c) comparing the first and second samples in order to provide an input sample comparison;

    (d) repeating steps (a)-(c) in order to provide a plurality of input sample comparisons; and

    (e) adjusting the detection threshold in response to at least one of said input sample comparisons.
