Abstract:
1. A method of adjusting a receiver timing towards a signal timing of a data signal received at a receiver, said signal timing being a characteristic of said data signal, the method comprising: receiving the data signal using a receive mode operating in accordance with the receiver timing; determining, according to particular phase error algorithm, a first set of phase error indications indicating phase errors between the receiver timing and the signal timing of the received data signal, wherein the first set of phase error indications forms an error vector; applying a Fourier transform to the error vector; analysing the Fourier transform of the error vector to determine a frequency component of the error vector which identifies a frequency difference between the receiver timing and the signal timing; adjusting the receiver timing to a first adjusted receiver timing based on the identified frequency difference; determining an average of a second set of phase error indications indicating phase errors between the first adjusted receiver timing and the signal timing according to said particular phase error algorithm; and adjusting the first adjusted receiver timing to a second adjusted receiver timing based on the determined average of the second set of phase error indications.
