ABSTRACT:
Fast image rejection. Dual down conversion processing of a received signal by performing both low side injection and high side injection thereby generating a first down converted signal and a second down converted signal. Analysis of one or both of the first and second down converted signals, including the signal and image components thereof, is performed to determine which of the first down converted signal and the second down converted signal is appropriate to be selected for subsequent baseband processing. For example, if a signal strength of an image within the first down converted signal is less than a signal strength of a signal component within the first down converted signal, then the first down converted signal is most likely the appropriate signal to undergo baseband processing. Alternatively, if the converse is true, then the second down converted signal may be the appropriate signal to undergo baseband processing.
