Recent simulation results have shown that serial concatenation with outer codes such as cyclic redundancy check (CRC) or parity check (PC) codes can boost the error correcting performance of polar codes. A theoretical analysis for further explaining where the performance gain comes from is in order. In this paper, we try to provide such an analysis for concatenated polar codes from the distance spectrum...
With the development of high-speed trains (HST), efficient and reliable communication services in high mobility scenarios have become an urgent demand. As one of the strong candidates in 5G wireless system, polar codes along with its optimized design should also be investigated under high mobility scenarios. In this paper, a scheme of hash-concatenated polar codes is proposed to reduce the false alarm...
This paper is concerned with design of bit-interleaved coded-modulation (BICM) scheme with the use of 64-QAM and polar codes. Since one 64-QAM symbol carries six binary digits, we combine Arikan's kernel with a 3 × 3 kernel to form the generator matrix in avoidance of bit-puncturing. A joint design of bit-interleaver and the polar code is then proposed. The core of the design is to intensify the channel...
