A feed-forward symbol synchronizer (200, FIG. 2) samples symbols transmitted within one or more packets that form a burst of radio frequency (RF) energy. The symbol samples (209) are delayed in a data delay buffer (214) while a phase estimate (212) is generated for each packet. A resampler (218) resamples the delayed symbol samples based on the phase estimate, resulting in resampled data (228) that includes one sample per symbol. The resampled data is clocked into a dual-port RAM (230) using a resampling clock that is also based on the phase estimate. The resampled data is then clocked out of the dual-port RAM and into a demodulator (238) using the receiver's symbol clock (232). Also described are methods of operating the feed-forward symbol synchronizer.
A method for synchronizing symbols transmitted within one or more packets that form a burst of radio frequency (RF) energy, the method comprising:
A symbol synchronizer that synchronizes symbols transmitted within one or more packets that form a burst of radio frequency (RF) energy, the symbol synchronizer comprising:
A satellite within a satellite communications network that receives symbols transmitted within one or more packets that form a burst of radio frequency (RF) energy, the satellite comprising:
