SPREAD SPECTRUM DEMODULATOR USING BLOCK SIGNAL PROCESSING

摘要

This paper shows a Direct Sequence Spread-Spectrum (SS-DS) demodulator using block signal processing.Our proposed SSDS demodulator uses the block signal processing,unlike the conventional SS-DS demodulators using real time signal processing.Received signal demodulated quasi-coherently is once stored in memory,and after extracting matchedpulse timing and estimating carrier offset,the signal is demodulated.Incoming data,therefore,are all demodulated without being lost by the initial-acquisition time,and our proposed SS-DS demodulator can provide the high data transmission efficiency.
