摘要： The present invention is related to a method and apparatus for processing multiple wireless communication services in a receiver. A receiver receives more than one wireless communication service simultaneously via a wireless interface. Each service is transmitted via a different carrier frequency band. The multiple received carrier signals are down-converted to an intermediate frequency (IF) band using a mixer and a local oscillator (LO). The LO frequencies are set such that the down-converted IF bands of the multiple services are fallen into a single IF band.
