Abstract
Embodiment of the invention provides a receiving device having an intermediate frequency section to produce first and second intermediate frequency signals based on first and second received radio frequency signals, such that said intermediate frequency signals are combinable to be jointly processed. The first intermediate frequency signal is antipodal to the second intermediate frequency signal. Embodiment of the invention further provides at least one common sub-circuit to process at least one combined intermediate frequency signal which is based on components of first and second intermediate frequency signals.
Claims29
