摘要:

介绍了四相序列扩频调制与解调方法,并对四相序列扩频与QPSK在高斯白噪声信道条件下进行了仿真。仿真结果表明,该方案与传统的多进制正交扩频系统相比,大幅提高了数据的传输速率和抗干扰能力,可以较好地适用于高速数据通信。

Abstract:

A Quadriphase sequence spread spectrum modulation and demodulation method based on the principle of Quadriphase sequence is proposed in this paper.This method takes advantage of four-phase sequence and QPSK to simulate with Gaussian white noise channel.The experiment results demonstrate that,compared with multi-band orthogonal spread spectrum system,the method in this paper could greatly improve the capability of data transmission and capacity of resisting disturbance.This method is appropriate for high-speed data transmission.

Key words: quadriphase sequences;spread spectrum communication;high-speed data transmission
