| Abstract: | In order to achieve the phase-inversion symmetric and spread spectrum communication,according to the relativity of noise in time domain and the anti-noise theory of time domain phase-inversion,a hybrid structure of time domain phase-inversion symmetric and spread spectrum is proposed.The simulation and experimental results show that time domain phase-inversion symmetric and spread spectrum system can get higher output SNR and under the same transmission conditions,the phase-inversion symmetric spread spectrum technology is superior to the general spread spectrum technology.This method can find a wide use in mobile communications. |
