Abstract (en)

[origin: WO2006026249A2] 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 and sampling frequencies are adjusted such that the converted IF band signals of the input signals are spectrally adjacent or overlapping each other to some degree. SINAD of the services is measured at each of a plurality of spectrally overlapping conditions. The LO frequencies and the sampling frequency are then adjusted based on the SINAD measurement results.
