Improved Successive Cancellation Decoding of Polar Codes

  title={Improved Successive Cancellation Decoding of Polar Codes},
  author={Kai Chen and Kai Niu and Jiaru Lin},
  journal={IEEE Transactions on Communications},
As improved versions of the successive cancellation (SC) decoding algorithm, the successive cancellation list (SCL) decoding and the successive cancellation stack (SCS) decoding are used to improve the finite-length performance of polar codes. In this paper, unified descriptions of the SC, SCL, and SCS decoding algorithms are given as path search procedures on the code tree of polar codes. Combining the principles of SCL and SCS, a new decoding algorithm called the successive cancellation… CONTINUE READING
