Description: Convolutional Coding and Decoding Made Easy
I believe figure 6c and 6d should have input=0 in the caption rather than input=1. Also in 6d, the input state should be 001. Unless I miss something!
By the way, I really appreciate your tutorials. Very well written and intuitive! Many thanks.
Firstly I really appreciate your great tutorial. According to page 11, last paragraph describing how to encode 1101 using the state diagram, my question is why do we start from the MSB( from left to right)? like you wrote the arrival of 1 and then 0 and then 1 and finally 1?
Thanks for the tutorial….How to make trellis diagram for 2/3 or 3/4 etc convolution encoder…
i.e. how to make trellis diagram when input bit is more than one…as this is used in TCM
No other author has explained the coding and decoding theory with so much of clarity. One small clarification. The tree diagram on Page:13; 11(100)up 11(011) up 01(010) may have to be corrected as 11(100)up 11(010) up 01(001). Regret if I am giving a wrong suggestion.
Yes, you are correct. Need to go back and fix it. I am busy trying get my book out so it might be while.
Thank you very much for you comments, however.
very short and impressive note. Thank you!
Referring to the list of generator polynomials given on page 2. The number of binary bits for both G1 and G2 for a given constraint length are not matching. Why is this so?
