Construction and Decoding of Product Codes with Non-Systematic Polar Codes [PDF]
2019 IEEE Wireless Communications and Networking Conference (WCNC), 2019 Product codes are widespread in optical communications, thanks to their high throughput and good error-correction performance. Systematic polar codes have been recently considered as component codes for product codes. In this paper, we present a novel construction for product polar codes based on non-systematic polar codes.

Fast Software Polar Decoders [PDF]
, 2014 Among error-correcting codes, polar codes are the first to provably achieve channel capacity with an explicit construction. In this work, we present software implementations of a polar decoder that leverage the capabilities of modern general-purpose ...

Parallel concatenated systematic polar codes
Electronics Letters, 2016 A parallel concatenated coding structure, which can improve the performance of polar codes in finite‐length regime, is proposed. In the proposed structure, the encoder is built using two systematic polar codes (SPCs), and the decoder adopts iterative belief propagation decoding algorithm.

Secret Key Cryptosystem Based on Non-systematic Polar Codes [PDF]
Wireless Personal Communications, 2015 Polar codes are a new class of error correcting linear block codes, whose generator matrix is specified by the knowledge of transmission channel parameters, code length and code dimension. Moreover, regarding computational security, it is assumed that an attacker with a restricted processing power has unlimited access to the transmission media ...

Rateless Polar-Spinal Coding Scheme With Enhanced Information Unequal Error Protection
IEEE Access, 2019 In this paper, a rateless coding scheme with enhanced unequal error protection (UEP) property is proposed by concatenating the systematic polar code (SPC) and spinal code, where SPC is used as the outer code and spinal code is the inner code.

A Low Complexity Encoding Algorithm for Systematic Polar Codes [PDF]
IEEE Communications Letters, 2016 Arikan has shown that systematic polar codes (SPC) outperform nonsystematic polar codes (NSPC). However, the performance gain comes at the price of elevated encoding complexity, i.e., compared to NSPC, the available encoding methods for SPC require higher memory and computation. In this letter, we propose an efficient encoding algorithm requiring only $

Joint Source-Channel Polarization With Side Information
IEEE Access, 2018 As an extension of source polarization and channel polarization, this paper considers joint source-channel polarization, which results in a joint source-channel coding (JSCC) scheme using a quasiuniform systematic polar code (SPC).
