Patent ID: 7680215

Claim:
An apparatus, comprising: an adjustable front-end receiver; an adjustable analog filter (AF) coupled to the adjustable front end receiver, wherein the adjustable front end receiver and adjustable AF are adapted to receive frequency signaling throughout a first frequency bandwidth that includes a first carrier frequency to which the adjustable front end receiver is tuned; an analog-to-digital converter (ADC) coupled to the adjustable AF, wherein the ADC is adapted to convert an analog signal produced by the adjustable front end receiver and adjustable AF into a first digital signal within the first frequency bandwidth; a plurality of extraction units adapted to receive the first digital signal from the ADC, each of the plurality of extraction units adapted to extract from the first digital signal, a secondary digital signal having a frequency bandwidth equal to or narrower than the first frequency bandwidth, the secondary digital signal being associated with communication in at least one of a plurality of communication systems; a plurality of evaluation units and a plurality of detection units; a first control unit controlling a switching arrangement and fixing the frequencies and bandwidths of at least one of the plurality of the extraction units based on signals received from at least one of the plurality of the evaluation units and detection units; wherein each of the plurality of detection units is adapted to support a communication session in any of plurality of communication systems; and wherein each of the plurality of evaluation units is operable, while a detection unit is supporting the communication session, to evaluate another signal as a handover candidate.
