Design and implementation of airborne voice processing system based on ZYNQ platform
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.
