  • METHOD AND APPARATUS FOR COMPLEMENTARY CUMULATIVE DISTRIBUTION DRIVEN LEVEL CONVERGENCE FOR SPECTRUM SENSING
    Publication number: 20090135969
    Abstract: A method for use in a digital communications receiver for controlling an input signal level (200) into an analog-to-digital converter (ADC) initially receives a sample sequence (201) where a threshold crossing rate is measured as a percentage samples of an input signal that exceed the threshold (203). The error between the measured threshold crossing rate and a desired reference threshold crossing rate is calculated (205) and an error signal is then utilized in a feedback loop to control the receiver gain such that the error is reduced (207).
