A Novel Embedded Side Information Transmission Scheme Based on Polar Code for Peak-to-Average Power Ratio Reduction in Underwater Acoustic OFDM Communication System [PDF]
SensorsIn this paper, we proposed an embedded side information (SI) transmission scheme based on polar code construction for PAPR reduction using the PTS scheme in the underwater Acoustic (UWA) Orthogonal Frequency Division Multiplexing (OFDM) communication ...

Does Gaussian Approximation Work Well for the Long-Length Polar Code Construction?
IEEE Access, 2017 Gaussian approximation (GA) is widely used to construct polar codes. However, when the code length is long, the subchannel selection inaccuracy due to the calculation error of conventional approximate GA (AGA), which uses a two-segment approximation ...

Polarization and Polar Codes [PDF]
Foundations and Trends® in Communications and Information Theory, 2012 This tutorial treats the fundamentals of polarization theory and polar coding. Arikan’s original results on binary source and channel polarization methods are studied. Error probability and complexity analyses are offered. The original results are generalized in several directions.

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 ...

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 ...

On the construction of polar codes [PDF]
2011 IEEE International Symposium on Information Theory Proceedings, 2011 We consider the problem of efficiently constructing polar codes over binary memoryless symmetric (BMS) channels. The complexity of designing polar codes via an exact evaluation of the polarized channels to find which ones are "good" appears to be exponential in the block length.

Polar Coding for Processes With Memory [PDF]
IEEE Transactions on Information Theory, 2016 We study polar coding for stochastic processes with memory. For example, a process may be defined by the joint distribution of the input and output of a channel. The memory may be present in the channel, the input, or both. We show that $ψ$-mixing processes polarize under the standard Arıkan transform, under a mild condition.

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

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.
