Abstract:
A transceiver includes a channel estimator configured to generate, based on a packet received over a channel, an initial channel estimate for the channel. A compensator is configured to compensate a phase of the initial channel estimate to adjust for a carrier frequency offset associated with the channel, and ii) selectively compensate the initial channel estimate for sampling phase jitter. The selectively compensating the initial channel estimate for sampling phase jitter includes compensating the initial channel estimate for sampling phase jitter responsive to the packet having been received at a data rate greater than a first predetermined data rate, and not compensating the initial channel estimate for sampling phase jitter responsive to the packet having been received at a data rate less than or equal to the first predetermined data rate.
