Here the Viterbi Decoder is designed for faster decoding speed and less routing area with a special path management unit. The sys- tem is realized using Verilog HDL. It is simulated and synthesized using Modelsim Altera Starter Edition 6.6d and Xilinx 13.2 for RTL Design.Momin Inthiyaaz Ali...
The design complexities for the bit-pipelined architecture are evaluated and demonstrated using Verilog HDL simulation. And a general algorithm in software that simulates a Viterbi Decoder was developed. Our research is concerned with implementation of the Viterbi Decoders for Field Programmable Gate ...

The Viterbi Decoder block decodes convolutionally encoded input symbols to produce binary output symbols by using the Viterbi algorithm.
This example shows you how to use MATLAB® System objects and an HDL simulator to cosimulate a Viterbi decoder implemented in VHDL.The HDL Verifier™ product lets you verify the design implemented in Verilog or VHDL using MATLAB System objects. The product allows you to cosimulate t...
Define a puncture pattern matrix, and then reshape it into vector form for use with the encoder and decoder System objects. pPatternMat = [1 0 1;1 1 0]; pPatternVec = reshape(pPatternMat,6,1); Create a convolutional encoder and a Viterbi decoder in which the puncture pattern is defin...
