SLIDING INTERMEDIATE FREQUENCY (IF) RECEIVER WITH ADJUSTABLE DIVISION RATIO AND SLIDING IF RECEPTION METHOD

摘要

A sliding intermediate frequency (IF) receiver and a sliding IF reception method are provided. A first local oscillation signal and a second local oscillation signal may be generated, based on a division ratio of a frequency of the first local oscillation signal to a frequency of the second local oscillation signal that is determined in advance so that an amount of power to be consumed or an error rate of the sliding IF receiver is optimized. A received input signal may be converted to a first IF signal, based on the first local oscillation signal, and the first IF signal may be converted to a second IF signal, based on the second local oscillation signal.
