Abstract
A system including a circuit to compensate for sampling phase jitter. The system includes a channel estimator to determine, based on training symbols in a preamble of a data packet received via a communication channel, an estimate of the communication channel and a carrier frequency associated with the communication channel. The circuit compensates, based on the determined carrier frequency, a phase of the estimate of the communication channel to adjust for a carrier frequency offset associated with the communication channel, and, based on a data rate at which the data packet was received via the communication channel, selectively compensates the estimate of the communication channel for sampling phase jitter.
