Furthermore, a construction based on dynamically frozen bits with constraints among the \"low weight bits\" (LWB) is presented. Simulation results show that the LWB-polar codes outperform the CRCpolar codes and the eBCH-polar codes under SCL decoding....

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. ...
