Patent ID: 8422539

Claim:
A multi-carrier receiver, comprising: a first signal processing unit, having M first signal processing paths, and configured for performing a first signal processing to at least a radio frequency (RF) signal for outputting at least a sub-carrier signal, wherein the at least a RF signal is the aggregation of at least a sub-carrier signal and is adjusted by a carrier aggregation technique dynamically, wherein the sub-carrier signals are non-contiguous, and M is greater than 1; a router, having M input terminals and N output terminals, wherein the M input terminals are respectively coupled to the M first signal processing paths of the first signal processing unit for receiving the at least a sub-carrier signal, and are configured for selecting to output the at least a sub-carrier signal to the N output terminals, wherein the received signal at each of the N output terminals of the router comprises the sub-carrier signal at each of the M input terminals of the router, and N is greater than 1; and a second processing unit, having N second processing paths respectively coupled to the N output terminals of the router for performing a second signal processing to the at least a sub-carrier signal and outputting at least a digital signal.
