Abstract:
1. A method of regenerating a remotely transmitted signal comprising a symbol stream modulated onto a carrier in accordance with a predetermined standard, the method including the steps of: a) receiving the remotely transmitted signal having known characteristics; b) determining frame timing of the received signal; c) identifying the locations of one or more training sequences within the signal from the frame timing, the one or more training sequences including eight training sequences associated with data bursts and a ninth training sequence associated with dummy bursts containing no data; d) identifying the structure of the training sequences; e) estimating phase shift values at the locations of the sequences; f) demodulating the symbol stream using the structure of the sequences; g) detecting corrupted symbols in the symbol stream where prior knowledge of the symbol stream exists and correcting the symbol stream by substituting correct symbols for the corrupted symbols in the symbol stream; and h) remodulating the symbol stream using the phase shift values, wherein the training sequences include synchronization signals and frequency correction bursts.
