摘要： The method measures the time of arrival at a radiocommunication receiver of a received radio signal originating from a transmitting station. A received signal component is stored in a memory of the receiver. An estimation of the information bits carried by the signal component is obtained through demodulation of the signal component by the receiver. The estimation of the time of arrival of the signal is carried out on the basis of the bits thus estimated and the received signal component.

摘要： A cellular network infrastructure has radio network controllers and fixed transceivers serving respective cells. The proposed method of controlling radio resources assigned to a communication between a mobile terminal and such infrastructure comprises measuring parameters of respective propagation channels between the mobile terminal and a number of fixed transceivers. Report messages indicating at least some of the measured parameters are transmitted to the radio network controller to be processed. The measured parameters indicated in the report messages for at least one fixed transceiver include data representing a time variability of a power level received on the channel between the mobile terminal and this fixed transceiver.

摘要： Data blocks to be received each comprise a header and a data field including respectively first and second codes for error detection. The decoding of a signal segment received having first and second portions corresponding respectively to the header and to the data field of a block gave rise to a verification of the first code in the first portion. If the first code is correct, a check is made to verify whether the second portion of the decoded signal has a second correct code. A data block is considered to be detected either in the presence of first and second correct codes, or in the presence only of a first correct code when a data likelihood criterion, evaluated during the decoding of the second portion of the signal, is fulfilled.
