| 摘 要： | 根据噪声在时域上的相关性以及反相对称法的抗噪原理,将反相对称法与扩频通信相结合,提出了一种新的扩频通信方法。通过仿真和实验验证表明,时域反相对称扩频技术能使系统获得较高的输出信噪比,且在相同的传输条件下,反相对称扩频技术的性能优于一般的扩频技术。

| Abstract: | According to the relativity of noise in time domain and the antinoise principle of time domain phase-inversion symme-tric method,a novel spread spectrum communication method is proposed in combination with phase-inversion symmetric method and spread spectrum communication.The simulation and experimental verification indicate that the time domain phase-inversion symmetric and spread spectrum system can get higher output SNR,and under the same transmission conditions,capability of phase-inversion symmetric sp... |
