基于FPGA的数字语音通信系统设计

Digital Voice Communication System Design Based on FPGA

针对PCM编解码芯片接口设计,使用FPGA控制PCM编解码芯片实现语音的PCM编码和解码方法,并利用这种方法构建了一个数字语音通信系统,实现语音信号的实时无线传输。实验表明:该系统工作稳定,传输语音不失真,可用于无线电干扰比较严重的场合实现远程无线语音通信。

For the PCM encoder and decoder chip interface design,it proposed the method in which the FPGA is used to control PCM encoder and decoder chip realize PCM encoding and decoding.This method is used to build a digital voice communication system and realizes real-time wireless transmission of voice signal.Ex-periments show that the system work stable,transmission voice without the distortion.It can be used to realize remote wireless voice communication for radio interference serious occasion.
