A heuristic construction of polar codes for successive cancellation list (SCL) decoding with a given list size is proposed to balance the trade-off between performance measured in frame error rate (FER) and decoding complexity. Furthermore, a construction based on dynamically frozen bits with ...

This characteristic of list decoding demands a different approach in code construction. In this work, we modify the conventional construction by a greedy search algorithm in which a bit-swapping approach is employed to re-distribute the low-reliability bits in the subblocks aiming for a reduction ...

Over the years various polar code decoding algorithms, like SC-list (SCL), have been proposed to improve the mediocre performance of the successive cancellation (SC) decoding algorithm for finite code lengths; however, like SC, they suffer from long decoding latency. Fast decoding of polar codes...

The complexity reduction mainly comes from the following two facts: 1)Due to the symmetric code construction, the block length reduces from N to N/2; 2) Instead of the first bit, the backtrack operation starts from the (N/2+1)-th bit, which can dramatically reduce the visited nodes. ...
