<p>The present invention relates to a method for synchronizing a receiver with the frequency and phase of a received signal, said method comprising the steps of taking a sample of the received signal at predetermined intervals and selecting a decision sample (0) from the samples taken. To produce accurate and reliable synchronization, at least two samples are taken during the duration of one received symbol; a first reference sample (-1) is selected from the samples preceding the decision sample (0); a second reference sample (1) is selected from the samples subsequent to the decision sample; the difference (E) of the first (-1) and the second (1) reference samples is calculated; the difference is compared with the target value; and the sampling frequency is adjusted on the basis of the comparison.</p> |
