Huffman source coding with Simulink

Hi, I want to implement Huffman source coding in Simulink. But I am stuck. Which blocks do I need to use. Any help would be appreciated.

Hi,

Implementing Huffman code from scratch using Simulink Blocks can be a challenging task as calculating the frequencies of input character, and consequently building the Huffman tree is itself very challenging. From there on, encoding the string using only Simulink blocks possess another challenge.

Therefore, I would recommend you to use a MATLAB function block that uses the built-in 'huffmanenco' if you want to implement Huffman encoding in Simulink. Please refer to the following documentations for more information on the MATLAB function block, 'huffmanenco' and related functions:

1. https://www.mathworks.com/help/simulink/what-is-a-matlab-function-block.html
2. https://www.mathworks.com/help/comm/ref/huffmanenco.html
3. https://www.mathworks.com/help/comm/ref/huffmandeco.html
4. https://www.mathworks.com/help/comm/ref/huffmandict.html

Alternatilvely, you could also use the MATLAB function block to implement Huffman encoding from scratch for further modification. A comprehensive discussion on this can be found here: https://www.mathworks.com/support/search.html/answers/459170

I hope this helps!
