Soft-Decision Viterbi Decoding with Puncturing

Performs soft-decison Viterbi decoding with puncturing over an AWGN channel using Simulink(R).

Description

Implements soft-decision Viterbi decoding for a rate 3/4 code over an AWGN channel using Simulink(R).

The Viterbi decoder block from the Communications Blockset is enhanced to optimally support punctured codes.

The attached BERTool session file compares the BER performance as the number of bits are varied for the soft decision with the performance for unquantized inputs. The model file is set-up to support additional runs.

• Required Products: Communications Blockset; Communications System Toolbox; DSP System Toolbox; Signal Processing Toolbox; Simulink
• MATLAB release: MATLAB 7.2 (R2006a)

Hi dear sir!
i am also working on project in wireless communication and i am trying to implement soft decision veterbi encoding/decoding in Matlab, can you kindly help me in sending the matlab code.
thanks
waiting for your reply

Dear Amit,

I am just new to Soft-decision viterbi decoding.
I am using MATLAB vitdec() function to do the same.
Well, i am facing a problem that how to apply the depuncturing to the soft decisions (7,6,5,4,3,2,1,0) to decode properly. As this Matlab function input requires soft decisions only in these (7,6,5,4,3,2,1,0) range.
Please give a minute to it.
