扩频通信是现代通信系统中不可或缺的部分，用扩展频谱的方式可换取信噪比增益，从而提高通信系统的抗干扰能力。构建出直扩通信系统，通过示波器观察信号在传输过程中波形和频谱的变化，以验证是否实现扩频解扩功能；通过误码率的监测，验证了直扩系统抗高斯白噪声干扰和单频正弦波干扰的能力并进行分析。

The spread spectrum communication is indispensable in modern communication system , and the SNR gain can be reached through spread spectrum so as to improve anti-interference ability of the communica-tion system .A DSSS communication system was constructed and making use of the oscilloscope , the signal ’ s waveform and frequency spectrum changes in transmission were observed to verify spread spectrum algorithm functions .Error rate monitoring proves the spread spectrum system ’ s capability of resisting Gaussian white noise interference and single frequency sine wave interference .
