摘要
为了解决机载环境下飞行员通话强噪声干扰问题,提出了一种基于ZYNQ架构的数字话音处理系统。该系统由模拟处理单元和数字处理单元组成,模拟处理单元完成模拟语音信号的预处理、滤波和AD/DA转换;数字处理单元以国产ZYNQ处理器为核心,在ZYNQ-PL和ZYNQ-PS上运行数字话音处理算法,对数字音频信号进行自适应噪声抑制和话音增强处理。试验结果表明:该话音处理平台能够有效抑制飞行员通话噪声,对回声也有很好的抵消作用,提高了飞行员通话的舒适度。
In order to solve the problem of strong noise interference in pilot conversations in airborne environments,a digital voice processing system based on the ZYNQ architecture is proposed.The system consists of an analog processing unit and a digital processing unit,which completes the preprocessing,filtering,and AD/DA conversion of analog speech signals;The digital processing unit is based on a domestically produced ZYNQ processor,and runs digital voice processing algorithms on ZYNQ-PL and ZYNQ-PS to perform adaptive noise suppression and voice enhancement processing on digital audio signals.The experimental results show that the voice processing platform can effectively suppress pilot communication noise,have a good cancellation effect on echoes,and improve the comfort of pilot communication.
