Abstract :
As an example of convolutional code (2, 1, 5), designing of constitute the decoder module and the system with timing chart and VHDL, which obtains the corresponding simulation results. It is basing on the composition block diagram. Through the simulation results and performance analysis, the hard decision viterbi decoder has a strong error correction, high efficiency, stability, easy to implement extensions and etc.
