Receiver, sender, method and burst signal |
摘要 |
<p>Known burst signals exchanged between senders and receivers comprise either one syncronisation block followed by a data block or several equidistant synchronisation blocks separated by data blocks, with a synchronisation block including predefined synchronisation symbols and with a data block including data symbols. By adapting senders and receivers in such a way that said synchronisation blocks are being located non-equidistantly, preferably with a centre of gravity of synchronisation symbols mainly corresponding with a centre of said burst signal, an improved synchronisation can be reached. Thereto, senders and receivers comprise locators for locating said non-equidistant synchronisation blocks, with said receivers preferably further comprising determinators for determining phases of synchronisation blocks, and synchronisers for synchronising detectors/demodulators in dependence of neighbouring as well as non-neighbouring non-equidistant synchronisation blocks, and processor systems for calculating frequencies in dependence of locations and/or phases. Said processor systems preferably comprise estimators for in dependence estimating main frequencies. <IMAGE></p> |
