基于FPGA的可编程PCM解调器的设计

Design and Realization of PCM Demodulator Based on FPGA

介绍一种基于FPGA的可编程PCM解调器的设计,PCM解调器由位同步、字节同步、帧同步和串并转换等模块组成,由EP1C6Q240来实现其功能,解调出来的PCM数据通过USB总线发送给PC机进行数据的后台处理。结果表明:利用FPGA和USB总线实现PCM高码传输,在各种遥测系统中具有较强的实用价值。

A design of programmable PCM demodulator based on FPGA has introduced,PCM demodulator combine with bit synchronization,byte synchronization,frame synchronization and serial parallel conversion modules,using EP1C6Q240 to achieve its function,the data demodulated by the PCM are sent to the PC and processed in background through the USB bus.The results showed that：the use of FPGA and the USB bus to achieve high PCM code transmission in a variety of telemetry systems has a strong practical value.
