Abstract
Various embodiments of the present invention include methods and apparatus for receiving a radio frequency (RF) signal spectrum in a receiver; mixing the RF signal spectrum with a first local oscillator (LO) frequency to obtain a first downmixed signal; and converting the first downmixed signal to a first digital signal using an analog-to-digital converter (ADC) having an adjustable clock frequency selected to avoid interference with the first LO frequency. The adjustable clock frequency may be adjusted by a predetermined amount, by phase modulation, or in other manners.
