Polar Codes: From Theory to Practice

Channel coding is a pivotal technique employed to account for potential errors due to channel noise or interference by adding layers of redundancy to information prior to transmission or storage. Should errors appear in the transmitted sequence upon reaching its destination, they can be corrected with reference to the redundant layers. Polar codes are a new class of error correction codes that provably achieve the capacity of binary discrete memoryless channels. Their distinct advantages have led to their incorporation in the logical control channels of the fifth generation of wireless communications (5G). Possessing robust and competitive error correction capabilities for short and medium-length codes positions them strategically to fulfill a pivotal role in various communication systems as we move towards the sixth generation of wireless communication (6G) and beyond.
