ABSTRACT:
With an object being the overall reduction of error in systems wherein reception timing is controlled by detecting the timing error of the received signal even when the signal arrival path varies in multipath communication and similar conditions, the present invention comprises a timing error detection means 3 which detects errors between the time slot reception time and reception timing of the received signal, a reception timing control means 1 which controls the reception timing of the slot on the basis of errors at reception of preceding time slots, and a control adjustment means 2 which adjusts the amount of control of the reception timing in relation to the errors detected, the control adjustment means 2 making it possible, by taking the time average of each error detected during reception of a plurality of time slots, to fix the error in the vicinity of the maximum frequency of timing delay distribution, even where there are variations in error resulting from variations in the arrival path of the received signal in multipath communication and similar conditions, thus effectively facilitating the overall reduction of errors of reception timing in the receiver.
