摘要:
A system and method of performing re-synchronization for a Digital Video Broadcasting over Handheld (DVB-H) receiver, wherein the method comprises performing a time division multiplexing (TDM) data burst transmission sequence on bits of data received by the DVB-H receiver; performing a data bit re-synchronization sequence on the DVB-H receiver; removing an on-chip timer and internal state registers in the DVB-H receiver; and allowing the DVB-H receiver to power off in between receipt of data bursts. Preferably, the removing process reduces the time to perform the re-synchronization in the DVB-H receiver. Preferably, the data bit re-synchronization sequence comprises performing an automatic gain control (AGC) lock process; performing a mode and guard detecting process; performing a frequency offset estimation process; performing a transmit parameter signaling (TPS) detection process; performing a timing and carrier loop lock process; and performing an equalizer delay process.
