HANDSET TIME SYNCHRONIZATION TO A WIRELESS TELEPHONE BASE STATION |
摘要 |
<p>A wireless telephone system and related method are described, the system having a plurality of wireless handsets and a base unit, the base unit having a base transceiver, each handset having a handset transceiver for establishing a wireless link over a shared channel with the base unit via the base transceiver. The base unit transmits a signal comprising a current packet of a plurality of packets of an epoch. Each handset transceiver has a receiver having a parallel correlator for generating timing error signals and end-of-packet signals for the signal, and a timing loop for receiving the timing error signals and for establishing symbol-level timing synchronization. An enable resynch gate of the receiver receives the end-of-packet signals from the parallel correlator to establish packet-level synchronization, and a de-packetizer of the receiver reads epoch location information from the current packet which identifies the location of the current packet within the epoch. A counter of the receiver receives the epoch location from the de-packetizer and establishes epoch-level synchronization.</p> |
