: Used in MIMO (Multiple-Input Multiple-Output) systems to achieve diversity and high reliability by transmitting data across multiple antennas. Erasure Correcting Codes Luby Transform (LT) Raptor Codes

In 2008, Erdal Arıkan introduced Polar Codes, the first class of codes to provably achieve the Shannon capacity with low encoding/decoding complexity.

Understanding the PDF is step one. Implementation is step two. Modern Software Defined Radios (SDRs) and DSPs use libraries like:
