Patent ID: 8594240

Claim:
A receiver for receiving a communication channel modulated on one or more carrier frequencies, said receiver comprising: a radio frequency amplifier to amplify signals within a band of frequencies which band includes the one or more carrier frequencies; a current consumption adjustable analog to digital converter to convert the signals into a digital form; a wideband signal power measurement circuit to receive the output of said radio frequency amplifier and to generate a signal strength of said signals and/or noise signals in a spectral band corresponding with the band of frequencies amplified by said amplifier; a baseband signal power measurement circuit to measure power of a filtered baseband version of the received signal; and spectrum scanning and power measurement control logic to receive outputs of said wideband and said baseband measurement circuits, to classify interfering signals based on measured signal power and spectral proximity to the one or more channel carrier frequencies and to adjust the power mode of said radio frequency amplifier and/or the current consumption of the analog to digital converter based on the classification.
