Improved beacon signaling methods are described. Beacon signals are transmitted on the same tone in at least two consecutive symbol periods facilitating accurate energy measurements over a symbol period even if timing synchronization with the transmitter is not maintained. A low power wideband signal is also combined with the beacon signal to facilitate channel estimation and other operation such as timing synchronization operations.
L'invention concerne des procédés de signalisation par balise améliorés. Des signaux de balise sont transmis sur la même tonalité pendant au moins deux périodes de symbole consécutives, facilitant des mesures d'énergie précises pendant une période de symbole même si la synchronisation de rythme avec l'émetteur n'est pas maintenue. Un signal à large bande de faible puissance est combiné au signal de balise, de manière à faciliter l'estimation de canal et d'autres opérations telles que des opérations de synchronisation de rythme.
