摘要
Method for estimating and correcting a frequency offset between a local clock of a receiving transceiver and a remote clock of an emitting transceiver comprises receiving by said receiving transceiver, a signal emitted by the emitting transceiver, said signal lacking a continuous sinusoidal carrier and having at least one symbol, each symbol being emitted within a time frame having a first duration; sampling the signal by taking for each time frame a set of energy measurements of said signal; forming a matrix representative of said energy measurements; determining from said energy matrix, points of maximum of energy within each time frame; determining a line connecting a plurality of said points within each of said time frames; determining a slope of said line; calculating a frequency offset between the clocks of the emitting and receiving transceivers using the slope; and adjusting the receiving transceiver's clock frequency according to the frequency offset.
