    Abstract: In one embodiment, an apparatus includes a first receiver path with a first digitizer to digitize an incoming signal obtained from a radio frequency signal including at least a first desired channel into samples, the first digitizer to operate at a first sampling frequency, a first sample rate converter coupled to an output of the first digitizer to receive the samples at the first sampling frequency and to output the samples at a fixed sampling frequency, and a first digital processor to receive and process the samples at the fixed sampling frequency. The apparatus may further include a controller to receive a frequency change indication and to dynamically control the first sample rate converter to accommodate a change in the first sampling frequency from a first rate to a second rate.

    Abstract: In one embodiment, an apparatus includes: an antenna switch to receive a first radio frequency (RF) signal from a first antenna and a second RF signal from a second antenna and controllable to output a selected one of the first and second RF signals; an RF circuit to receive and process the first and second RF signals; at least one mixer to downconvert the first and second RF signals to first and second baseband signals; and an antenna diversity control circuit to receive sub-symbol portions of a first plurality of symbols of the first baseband signal and sub-symbol portions of a second plurality of symbols of the second baseband signal, and control the antenna switch to output one of the first and second RF signals, based at least in part on one or more of the sub-symbol portions of the first and second pluralities of symbols.
