System, Apparatus And Method For Acquisition Of Signals In Wireless Systems With Adverse Oscillator Variations

In one aspect, a radio device comprises: an analog front end (AFE) circuit to receive and process an incoming radio frequency (RF) signal comprising a packet; an analog-to-digital converter (ADC) coupled to the AFE circuit to receive and digitize the processed incoming RF signal into a digital signal; a detector coupled to the ADC to detect a carrier frequency offset (CFO) in the digital signal based at least in part on a preamble of the packet; and a controller coupled to the detector. The controller may generate a compensation value for the CFO based on the detected CFO and cause one or more components of the radio device to compensate for the CFO using the compensation value.
