Abstract
A method in a receiver includes receiving from a transmitter a signal including at least first and second frames that carry same data. First and second data symbols are identified in the respective first and second frames, wherein the first symbol has a same data value as the second data symbol. A frequency offset between the transmitter and the receiver is estimated based at least on the identified first and second data symbols. A frequency of the receiver is adjusted based on the estimated frequency offset.

A method, comprising:
- in a receiver, receiving from a transmitter a signal comprising at least first and second frames that carry same data;
- identifying in the first and second frames respective first and second data symbols, wherein the first symbol has a same data value as the second data symbol;
- estimating a frequency offset between the transmitter and the receiver based at least on the identified first and second data symbols;
- and
- adjusting a frequency of the receiver based on the estimated frequency offset.
2 more elements
A receiver, comprising:
- a front end, which is configured to receive from a transmitter a signal comprising at least first and second frames that carry same data;
- and
- a processor, which is configured to identify in the first and second frames respective first and second data symbols, wherein the second data symbol has a same data value as the first data symbol, to estimate a frequency offset between the transmitter and the receiver based on the identified first and second data symbols, and to adjust a frequency of the receiver based at least on the estimated frequency offset.
