Direct-Sequence Spread-Spectrum (DSSS) burst modulator/demodulator
Burst mode operation:
fixed-length 512-bit data frames from/to LAN/UDP ports
Multiple frames transmitted efficiently with only 32-symbol separation.
Acquisition: 1600-symbol preamble with no apriori knowledge of arrival time
Large frequency acquisition range: ±(chip_rate / 64) or (1.8*symbol_rate),
whichever is smaller, with no apriori knowedge.
