Abstract
The digital multiplexer is an essential component part in the satellite communication.With the hardware description language(VHDL) and hardware programmable device,using the time-sharing multiplying technology,one kind of multiplexing and demultiplexing design scheme for multi-channel digital signals such as video data,audio data,synchronous data,asynchronous data,local area network(LAN) data,etc.is proposed in the portable digital satellite communication system.The simulated result is given and analysis on synchronous performance is also carried out.Finally,this paper describes in detail the key points and issues in design and implementation process.
