ABSTRACT:
A synchronous transmitter and receiver utilizing a spread spectrum communication method includes a pseudo noise code generator for generating a preset pseudo noise (PN) code; a spectrum spreading device for band-spreading input data in accordance with a pseudo noise code; a modulator for modulating an intermediate frequency signal to an in-phase and a quadrature phase by means of the pseudo noise code and spread spectrum data according to a quadrature phase shift keying modulation method; and a transmitter for transmitting a carrier wave modulated by the modulated signal.
