Abstract

A direct-sequence spread-spectrum (DS-SS) demodulator using block signal processing is presented. The proposed DS-SS signal processing is unlike the conventional DS-SS demodulators, which use real time signal processing. The signal is modulated quasi-coherently and stored in the memory. After extracting matched-pulse timing and estimating carrier offset, the signal is demodulated. Incoming data, therefore, are demodulated without being lost by the initial-acquisition time, and the proposed DS-SS demodulator can provide high data transmission efficiency
