摘要:
A receiver includes: 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) to receive and digitize the processed incoming RF signal into a digital signal; a packet detector to detect the packet; an estimation circuit to determine a carrier frequency offset (CFO) estimate based at least in part on a preamble of the packet; an averager to determine a CFO average value for a plurality of packets communicated between a device pair combination of the receiver and a transmitter; and a compensation circuit to compensate for CFO between the device pair combination based at least in part on the CFO average value.
