Patent ID: 8611445

Claim:
A receiver comprising: a first low-noise amplifier (LNA) to receive a first wireless signal from a first antenna, and to generate a first amplified signal; a second LNA to receive a second wireless signal from a second antenna, and to generate a second amplified signal; a multiplexer to receive the first amplified signal and the second amplified signal and to provide one of the first amplified signal and the second amplified signal as an output; a first in-phase receive processing block to process the first amplified signal to generate a first set of digital values representing a first in-phase baseband signal; a first quadrature-phase receive processing block to process the first amplified signal to generate a second set of digital values representing a first quadrature-phase baseband signal; a second in-phase processing receive block to process the output of the multiplexer to generate a third set of digital values representing a second in-phase baseband signal; a second quadrature-phase receive processing block to process the output of the multiplexer to generate a fourth set of digital values representing a second quadrature-phase baseband signal; and a baseband processor to process the first set of digital values, the second set of digital values, the third set of digital values and the fourth set of digital values, wherein, in a multiple-input multiple-output (MIMO) mode of operation of the wireless receiver, the multiplexer is configurable to provide the second amplified signal as the output, the baseband processor processing the first set of digital values and the second set of digital values to extract information contained in the first wireless signal and processing the third set of digital values and the fourth set of digital values to extract information contained in the second wireless signal, wherein, in a single-input single-output (SISO) mode of operation of the wireless receiver, the multiplexer is configurable to provide the first amplified signal as the output, the baseband processor processing the first set of digital values, the second set of digital values, the third set of digital values and the fourth set of digital values to extract information contained in the first wireless signal.
