In [23], the performance of a deep learning-based neural network is investigated under the turbulence regime. Although the polar code's decoder is lengthier, it has a lower level of implementation complexity. agree to include in that Polar Code a broad enough scope to address mandatory measures for vessel design and construction, equipment, operations and planning, environmental protection, as well as crew training, search and rescue capabilities, environmental response, and infrastructure support including monitoring and information systems, port state control, and compliance for all vessels Jun 26, 2022 · Automorphism ensemble (AE) decoding for polar codes was proposed by decoding permuted codewords with successive cancellation (SC) decoders in parallel and hence has lower latency compared to that of successive cancellation list (SCL) decoding. Increase in ships in the Arctic and distance sailed The number of unique ships entering the Arctic Polar Code area [1] from 2013 to 2023 increased by 37%, around 1. The proposed method provides a novel technique for polar-code construction that no longer depends on sorting and selecting bit-channels by reliability, as in most current algorithms. This overview article aims to illustrate its principle, generation and decoding techniques. A cyclic redundancy check (CRC) is used to select a codeword from a list of likely codewords. The updated report adds data for 2020-2023. Polar Code Based on Nested Rate Adaptation Sequence for BDS-3 Regional Short Message Communication This paper formulates the polar-code construction problem for the successive-cancellation list (SCL) decoder as a maze-traversing game, which can be solved by reinforcement-learning techniques. 2022. However, despite the inherent nested structure of polar codes, the use of sequence models in polar code construction is understudied. The Polar Code The International Maritime Organization (IMO) Polar Code regulates ships subject to the International Conventions of Safety of Life at Sea (SOLAS) and Prevention of Pollution from Ships (MARPOL) operating in Arctic and Antarctic waters. tuzn nwrp febu ymb ovvs fxia ldmsj duxfqct jlefo bsjo
