Polar Encoding

Polar coding of the input message.

polar encoding

Description

The Polar Encoding block performs polar coding of the input message in accordance with section 5.3.1 of the standard [1]. The block processes the input data, adds auxiliary bits that are used in the polar coding process, performs interleaving and performs encoding usage of the Arikan matrix. The auxiliary bits have specific values (usually 0) and do not contain information to be transmitted.
