Analysis on the Hybrid Technology of Time Domain Phase-Inversion Symmetric and Spread Spectrum

In order to realize the phase-inversion symmetric spread spectrum communication technology, this paper proposed a new spread spectrum communication method by combining the phase-inversion symmetric method and the spread spectrum communication according to the noise relativity in time domain and the anti-noise principle of phase-inversion symmetric method. Through the simulation and experimental verification, finally the systemic model is made. Result shows that time domain phase-inversion symmetric spread spectrum system can get higher output SNR, and under the same transmission conditions the capability of phase-inversion symmetric spread spectrum technology is superior to the general spread spectrum technology. This communication method can be widely applied in mobile communications.
