Low Constraint Length and High Performance Viterbi Decoder Using VHDL
In this paper, the authors deal with error correcting techniques in communication network. In digital electronics, the error correcting techniques plays a vital role in communication channels. The type of error correcting techniques that are considered in this paper is convolution encoder and Viterbi decoder. The Viterbi decoder is designed to decode the encode data. By using convolution encoder, length k and code rate of k/n can be simulated by using Xilinx and ModelSim 10.1b.
