Patent ID: 8194788

Claim:
A receiver, comprising a multi-branch correction preprocess module, a digital receiving path post-stage, and a multi-branch correcting and switching module; wherein the multi-branch correcting and switching module comprises: an amplitude and phase correction module, configured to obtain corrected M digital baseband signals according to the M digital baseband signals outputted from the multi-branch correction preprocess module and M amplitude and phase correction coefficients in the amplitude and phase correction module, and output the corrected M digital baseband signals to an M-to-1 Multiplexer module; an M-to-1 Multiplexer control module, configured to generate a switching control signal carrying an index of a branch according to the M digital baseband signals outputted from the multi-branch correction preprocess module and a switching strategy, and output the switching control signal to the M-to-1 Multiplexer module; and the M-to-1 Multiplexer module, configured to select one of the corrected M digital baseband signals outputted from the amplitude and phase correction module according to the switching control signal outputted from the M-to-1 Multiplexer control module, and output the selected digital baseband signal to a digital receiving path post-stage; wherein M is a positive integer greater than 1.
