LOW-COMPLEXITY SHORTENING METHOD FOR POLAR CODES
Encoding information with error correcting codes provides abilities to control the integrity of transmitted messages and to correct errors that appeared during transmission over noise channel. Polar codes are the first class of capacity achieving codes. The practical usage of polar codes in wireless systems faces the challenge of building code with codeword length different from an integer power of two. The paper reports efforts towards the design of polar codes with arbitrary codeword length. We propose a simple efficient scheme for shortening systematic polar codes, making polar codewords be easily adapted to any size.
