Cascade Coding

[iute]

Have you studied cascade coding?

[xdsopl]

Never have heard of it before. Can you elaborate or provide a paper about it?

[iute]

Sorry, I may have translated it wrong, it may be called cascade code, which is a combination of two error correction codes. As an example, here's a paper from a long time ago, called"Performance of RS-BCH Concatenated Codes and BCH Single-Stage Codes on an Interference Satellite Channel"

I am studying FEC, if I don't know any questions can I ask you?

[xdsopl]

Ahh, yes, cascade != concatenate. Concatenating codes is a well know technique to combine an practically soft decodable (usually a convolutional or LDPC) inner code with an hard decodable, (usually BCH or RS) algebraic outer code to improve the error floor or burst error behavior of the inner code: https://en.wikipedia.org/wiki/Concatenated_error_correction_code

Thanks for the explanation, but I didn't find the code information of the concatenating codes on github, or maybe I searched for the wrong keywords, what should I do?

Learning how to search and where to look is part of your studies. You have to do that yourself. Good luck!
