A radio receiver includes a first diversity antenna structure, a second diversity antenna structure, a first RF receiver section, a second RF receiver section, a combining module, and a baseband processing module. The first diversity antenna structure includes a plurality of first antennas and each of the plurality of first antennas is operably coupled to receive inbound radio frequency (RF) signals, wherein the first diversity antenna structure provides the received inbound RF signals from one of the plurality of first antennas based on a first antenna selection signal to produce first received inbound RF signals. The second diversity antenna structure includes a plurality of second antennas and each of the plurality of second antennas is operably coupled to receive the inbound RF signals, wherein the second diversity antenna structure provides the received inbound RF signals from one of the plurality of second antennas based on a second antenna selection signal to produce second received inbound RF signals. The first RF receiver section is operably coupled to convert the first received inbound RF signals into first inbound baseband signals. The second RF receiver section is operably coupled to convert the second received inbound RF signals into second inbound baseband signals. The combining module is operably coupled to combine the first and second inbound baseband signals to produce inbound baseband signals. The baseband processing module is operably coupled to convert the inbound baseband signals into inbound data and to produce the first and second antenna selection signals based on signal integrity of the first and second diversity antenna structures, respectively.
