1. A method for providing for determining the time of receipt of a received signal, the method comprising:
- using at least one processor to determine a receive time error by using a phase characteristic associated with a received phase angle at which a received signal is initially sampled together with the frequency of the received signal, the receive time error representative of the time taken for the received signal to travel between a reference phase angle and the received phase angle so as to provide for determining the time of receipt of the received signal.

Abstract
Methods and apparatus for providing for determining the time of receipt of a received signal are described. In particular, there is described method and apparatus for receiving a signal, and using a phase characteristic, such as the received phase angle at which a received signal is initially sampled, together with the frequency of the received signal in order to determine a receive time error. The receive time error can then subsequently be used to determine the actual time of receipt of the received signal.
