摘　　要：本文针对短波话音通信背景噪音较大的固有问题，目前已采用语音低速编码技术来实现声码数字话音通信，可以基本消除噪音的干扰；对于传统模拟话音通信，采用本文研究的增益约束数字降噪技术，也可以有效抑制噪音的干扰，提高语音通信质量和人听觉的舒适度。Since the background noise is relatively large in short-wave communication, the low speed voice encoding technology has been applied in vocoder digital voice communication, which may mostly reduce the noise interference. As for the traditional analog voice communication, the technology of gain constrained digital noise reduction discussed in this paper can also effectively reduce the noise interference and improve the quality of voice communication and the listening comfort.
