摘要： The present invention provides a method for determining a local oscillator frequency for a baseband converter, comprising obtaining characteristics of a channel comprising a plurality of radio signals at corresponding radio frequencies; using the channel characteristics to select a local oscillator frequency to use in baseband conversion of the plurality of radio signals of the channel to form a first baseband converted signal and a second baseband converted signal; and programming a local oscillator to operate the selected local oscillator frequency; wherein the local oscillator frequency is selected such that an image rejection ratio of the baseband converted second signal to an image of the baseband converted first signal is above a predetermined threshold.
