摘　　要：为了研究数据复接和分接,设计采用基于自由空间光通信系统的多路语音数据复接实现方案。该方案充分发挥了自由空间光通信技术的优势,利用现场可编程技术,结合了电话线传输系统,其中现场可编程门阵列控制模块由Verilog语言完成,且利用QUARTUSⅡ软件进行了仿真,达到提高信道利用率、扩大传输容量的结果。结果表明,该系统可传输30路语音信号。In order to study multiplexers, the design and implementation of coalition of multi-route data and voice based on free space optical communication （FSO）was introduced . Combining FSO teehnical advantages with telephone line transmission system, the compound interface between digital signal and voice was implemented based on field programmable gate array（FPGA）. The FPGA was programmed with Verilog hardware description language （ HDL ） , and the whole trajectory was simulated with QUARTUSⅡsoflware. As a result, the channel efficiency was promoted and the transfer capacity was increased because of the capability of digital multiple connection. The results show that the system is able to transfer 30-channel audio signal.
