이 편지에서는 4Tb/in에 대한 상호 정보 근사화(MIA)를 기반으로 한 폴라 코드 구성 방법을 제안합니다.2 비트 패턴 자기 기록(BPMR) 및 2차원 자기 기록(TDMR)과 같은 2차원 기호 간 간섭(2D-ISI) 채널. 기본 아이디어는 2D 검출기의 입력과 출력 사이의 MIA를 활용하여 MIA 결과를 기반으로 LLR(로그 우도 비율) 분포 모델을 설정하고 4D ISI 채널로 인해 발생한 격차를 보상하는 것입니다. 결과적으로, AWGN(Additive White Gaussian Noise) 채널을 위해 이전에 개발된 최적화 기술로 얻은 폴라 코드는 XNUMXD-ISI 채널에서도 만족스러운 성능을 가질 수 있습니다. 시뮬레이션 결과는 제안된 폴라 코드가 기존 방법으로 생성된 폴라 코드보다 XNUMXTb/in 이상의 성능을 발휘할 수 있음을 보여줍니다.2 2D-ISI 채널.

Abstract: In this letter, a method for the construction of polar codes based on the mutual information approximation (MIA) is proposed for the 4Tb/in2 two-dimensional inter-symbol interference (2D-ISI) channels, such as the bit-patterned magnetic recording (BPMR) and two-dimensional magnetic recording (TDMR). The basic idea is to exploit the MIA between the input and output of a 2D detector to establish a log-likelihood ratio (LLR) distribution model based on the MIA results, which compensates the gap caused by the 2D ISI channel. Consequently, the polar codes obtained by the optimization techniques previously developed for the additive white Gaussian noise (AWGN) channels can also have satisfactory performances over 2D-ISI channels. Simulated results show that the proposed polar codes can outperform the polar codes constructed by the traditional methods over 4Tb/in2 2D-ISI channels.
