ABSTRACT:
One embodiment of the present subject matter includes a method of receiving an input signal. The method, in various embodiments, includes detecting a peak of the input signal and detecting an envelope of the input signal. In various embodiments, the peak and envelope are used to identify out-of-band blocking signals and to adjust gain control. The method also includes comparing the peak to a first threshold Tp and comparing the envelope to a second threshold Te. In the method, if the peak is above the first threshold and the envelope is below the second threshold, then ignoring the input signal. If the envelope is above the second threshold, the method includes applying automatic gain control to decode information encoded in the input signal.
