Abstract

A time drift in sampling a received signal that is caused by a relative difference between a transmitter clock and a receiver clock is compensated by estimating a frequency offset between the transmitter clock and the receiver clock, and using the estimated frequency offset to determine a time drift estimate. The time drift estimate is then used to adjust a sampling phase during receipt of the signal. This adjustment may be performed for each sample. Alternatively, the adjustment may be performed only after first receiving a number of samples.
