METHOD AND SYSTEM FOR SYNCHRONIZATION IN A COMMUNICATION SYSTEM

摘要

The present invention relates to a method for uplink synchronization of a first transceiver and a second transceiver in a multi-user cellular communication system wherein communication resources are divided into communication channels. The method including the steps of: transmitting a first signature sequence from the second transceiver to the first transceiver, wherein said signature sequence is selected from a first set of signature sequences£=in the first transceiver, correlating the received signal with at least one signature sequence from a second set of signature sequences to estimate the time of arrival of said signature sequence to synchronize transmission between the second transceiver and the first transceiver. In said step of transmitting a first signature sequence from the second transceiver to the first transceiver a said first signature sequence constitutes at least part of a zero-correlation zone sequence. The invention also relates to a system and a transmitter.
