REAL-TIME VOICE NOISE REDUCTION SYSTEM APPLIED TO GROUND-TO-AIR COMMUNICATION

Disclosed is a real-time voice noise reduction system applied to ground-to-air communication， comprising a power supply， a voice input interface， a voice output interface， an audio AD/DA converter， and a noise reduction processing unit. The power supply is used for receiving input of an external power supply， and supplies power to the voice input interface， the voice output interface， the audio AD/DA converter， and the noise reduction processing unit; the voice input interface is used for receiving an audio signal; the audio AD/ DA converter is used for converting the audio signal into a digital signal and sending same to the noise reduction processing unit; the noise reduction processing unit performs noise reduction processing on the digital signal， and generates a noise reduction voice and sends same to the audio AD/DA converter; the audio AD/DA converter converts the noise reduction voice into an analog signal; the voice output interface is used for outputting the analog signal to the outside.本发明公开了一种应用于地空通信的实时语音降噪系统，包括电源模块、语音输入接口、语音输出接口、音频AD/DA转换器以及降噪处理单元。所述电源用于接收外部电源输入，并为语音输入接口、语音输出接口、音频AD/DA转换器及降噪处理单元供电；语音输入接口用于接收音频信号；音频AD/DA转换器用于将该音频信号转换为数字信号并发送至降噪处理单元；降噪处理单元对该数字信号执行降噪处理，生成降噪语音并将其发送至音频AD/DA转换器；音频AD/DA转换器将降噪语音转换为模拟信号；语音输出接口用于将该模拟信号向外输出。
