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 $

Adding a Rate‐1 Third Dimension to Parallel Concatenated Systematic Polar Code: 3D Polar Code [PDF]
Wireless Communications and Mobile Computing, 2018 In this paper, a three‐dimensional polar code (3D‐PC) scheme is proposed to improve the error floor performance of parallel concatenated systematic polar code (PCSPC). The proposed 3D‐PC is constructed by serially concatenating the PCSPC with a rate‐1 third dimension, where only a fraction λ of parity bits of PCSPC are extracted to participate in the ...

On the Error Performance of Systematic Polar Codes
CoRR, 2015 Systematic polar codes are shown to outperform non-systematic polar codes in terms of the bit-error-rate (BER) performance. However theoretically the mechanism behind the better performance of systematic polar codes is not yet clear. In this paper, we set the theoretical framework to analyze the performance of systematic polar codes.

Performance Analysis of CRC Codes for Systematic and Nonsystematic Polar Codes with List Decoding [PDF]
Wireless Communications and Mobile Computing, 2018 Successive cancellation list (SCL) decoding of polar codes is an effective approach that can significantly outperform the original successive cancellation (SC) decoding, provided that proper cyclic redundancy‐check (CRC) codes are employed at the stage of candidate selection.

Achieving the Uniform Rate Region of General Multiple Access Channels by Polar Coding [PDF]
, 2016 We consider the problem of polar coding for transmission over $m$-user multiple access channels. In the proposed scheme, all users encode their messages using a polar encoder, while a multi-user successive cancellation decoder is deployed at the receiver.

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.

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).
