1. A method for receiving transmitted signals in a CDMA communication system having a detector threshold for comparing with the detector threshold calculations made in accordance 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 input sample of the received signal at a first sample time;

    (b) obtaining a second input sample of the received signal at a second sample time;

    (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 detector threshold in response to at least one of said input sample comparisons, thereby providing an adjustment of the detection threshold in response to detection of said CW interference.
