| Abstract(in English) | A new family of codes, called polar codes, has recently been proposed by Arikan, as an answer to the problem of constructing a channel coding method with low-complexity encoding and decoding, along with the capacity-achieving property. The computational complexity is O(N log N) for encoding as well as decoding of polar codes, where N is the codelength. Polar codes are also proved to asymptotically saturate symmetric capacity of an arbitrary binary-input memoryless channel. We discuss basic properties of polar codes, including channel polarization, which is the basis of polar codes and their capacity-achieving property, and review research activities of polar codes. |
