RADIO COMMUNICATION RECEIVER APPARATUS AND METHOD

摘要

A radio communication receiver apparatus is configured to process multiple radio frequency bands in a telecommunication system. The apparatus includes a plurality of digital receiver chains wherein each digital receiver chain is coupled to receive a digital representation of the multiple radio frequency bands, including a particular radio frequency band for processing by the respective digital receiver chain. Each digital receiver chain includes a digital receiver that is programmable to select a particular radio frequency band from the digital representation of the multiple radio frequency bands, and configured to down convert the selected radio frequency band into a digital baseband signal associated with the particular radio frequency band. Built in calibration is provided by operation of direct radio frequency technology.
