Serially Concatenated Polar Codes
IEEE Access, 2018 Simulation results show that the performance of polar codes is improved vastly by using polar codes as inner codes in serially concatenated coding schemes.

Concatenated Polar codes [PDF]
2010 IEEE International Symposium on Information Theory, 2010 Polar codes have attracted much recent attention as the first codes with low computational complexity that provably achieve optimal rate-regions for a large class of information-theoretic problems. One significant drawback, however, is that for current constructions the probability of error decays sub-exponentially in the block-length (more detailed ...

Polar Codes’ Simplicity, Random Codes’ Durability [PDF]
IEEE Transactions on Information Theory, 2021 Over any discrete memoryless channel, we build codes such that: for one, their block error probabilities and code rates scale like random codes'; and for two, their encoding and decoding complexities scale like polar codes'. Quantitatively, for any constants $ , >0$ such that $ +2 <1$, we construct a sequence of error correction codes with ...

Research of Polar Codes Based on Binary Symmetric Channel [PDF]
Jisuanji gongcheng, 2019 The exisiting polar code construction scheme is only applicable to Binary Erasure Channel (BEC) and Additive White Gaussian Noise(AWGN) channel.Therefore,the constrution scheme of polar code in Binary Symmetric Channel (BSC) is studied.The construction ...

Effectiveness of the Polar Code Training of Cruise Liner Crew for Evacuation in the Arctic and Antarctic [PDF]
TransNav, 2020 In the past decades, we have seen a prolific increase in Polar Cruise Tourism, and thereby, more humans are able to visit the Polar Regions. As a result of this, the IMO implemented the Polar Code in 2017 to better prepare seafarers in polar waters in ...

IEEE Transactions on Communications, 2013 A framework is proposed that allows for a joint description and optimization of both binary polar coding and $2^m$-ary digital pulse-amplitude modulation (PAM) schemes such as multilevel coding (MLC) and bit-interleaved coded modulation (BICM). The conceptual equivalence of polar coding and multilevel coding is pointed out in detail.

Improving Polar-Coded SCMA System by Information Coupling and Parity Check
Sensors, 2020 In this paper, the uplink information-coupled polar-coded sparse code multiple access (PC-SCMA) system is proposed. For this system, we first design the encoding method of systematic joint parity check and CRC-aided (PCCA) polar code.

IEEE Communications Letters, 2011 Polar codes were originally introduced as a class of non-systematic linear block codes. This paper gives encoding and decoding methods for systematic polar coding that preserve the low-complexity nature of non-systematic polar coding while guaranteeing the same frame error rate.

Neural-Network-Assisted Polar Code Decoding Schemes
Applied Sciences, 2022 The traditional fast successive-cancellation (SC) decoding algorithm can effectively reduce the decoding steps, but the decoding adopts a sub-optimal algorithm, so it cannot improve the bit error performance. In order to improve the bit error performance

The Polar Code's Implications for Safe Ship Operations in the Arctic Region [PDF]
TransNav, 2020 Simultaneously with a decreasing sea ice cover in the Arctic region an increase in ship traffic is experienced in these waters, meaning a higher probability of accidents and incidents to occur. The capability to handle emergency situations for shipowners,
