Rate Matching Polar
Rate matching for an input polar coded message.
Description
The Rate Matching Polar block performs rate matching for an input polar coded message. As a result, the input coded message is converted to an output message of a given length by usage of bit repetition, truncation or shortening techniques. This block implements the algorithm from section 5.4.1 of the standard [1], ensuring correct rate matching for further transmission or data processing.
