摘　　要：提出了一个时分复用传输系统收发两端的结构原理图,介绍了核心器件DSP和CPLD,设计了一个基于特殊帧结构的时分复用传输系统来传输视频信号、语音信号和数据信号。整个系统由发射、接收2块电路单元和光纤传输单元组成,阐述了系统的工作原理。The structure principle of receiving end and sending end in a time multiplexing transmission system is introduced,and the core apparatus DSP and CPLD are introduced too. Time multiplexing transmission system with special frame structure is designed to transmit video frequency signals,voice signals and data signals. The whole system consists of two cells of transmitting circuit and receiving circuit and fiber optic transmitting cell. Its operating principle in this system is expounded.
