A new method of frequency offset correction using coherent averaging

Gajewski P., Łopatka J., Piotrkowski Z.

Journal of Telecommunications and Information Technology

2005

nr 1

142-146

This paper describes a new method of frequency offset correction to improve clock stability in communication systems where the temporary drift or jitter of phase angle is not accepted. This method bases on coherent spectral averaging with a special phase scanning algorithm. Achieved results show that proposed method is effective for strongly degraded signals. Method is useful for precise phase angle reconstruction in these systems where clock stability of the transceiver and receiver is insufficient.
