Abstract

This article proposes a known bits puncturing scheme for systematic polar code. The puncturing deteriorates BER performance because the removed bits are generally unknown at the receiving side. Polar code supports systematic encoding which generate the codeword that has the same value of information bits. Exploiting this characteristic, known bits, which are pre-shared between the transmitter and the receiver, are punctured from the codeword. The receiving side then set punctured bits to the known values and it can assist the decoding capability. Computer simulation verifies its effectiveness in terms of BER as well as throughput performance.
