With more and more systems are realized through digital technology,error-correction coding is also wided used. The channel mistake yard in wireless communication, can cause to transmit quality drop .the communication with normal influence. To control channel accidentally yard rate, there are two methods: One is to use to increase the signal-to-noise ratio that projects power to raise channel, another method is to be able to solve through the method of the coding of error correction.
This paper has described how to realize RS encoder in digital communication system. This scheme application Max+plusII software emulation have realized RS encoder function, it not only has distinct principle , and can be visual to describe coding effect. Show as a result: Apply Max+plusII [7,3,5]RS of software simulated realization yard encoder accord with coding algorithm, reach the purpose of the coding .
The development tool of this system is Max+plusII. Through Max+plusII modular and VHDL programming, borrow Max+plusII the logic with powerful emulation function, want the effect and goal that reaches visual have expressed come out.
