Distributed Joint Source-Channel Coding Using Quasi-Uniform Systematic Polar Codes [PDF]

Entropy, 2018
This paper proposes a distributed joint source-channel coding (DJSCC) scheme using polar-like codes. In the proposed scheme, each distributed source encodes source message with a quasi-uniform systematic polar code (QSPC) or a punctured QSPC, and only ...

Flexible and Low-Complexity Encoding and Decoding of Systematic Polar Codes [PDF]

IEEE Transactions on Communications, 2016
In this work, we present hardware and software implementations of flexible polar systematic encoders and decoders. The proposed implementations operate on polar codes of any length less than a maximum and of any rate.

Rate‐compatible systematic polar codes

IET Communications, 2021
Puncturing and shortening are two common ways to achieve rate‐compatible non‐systematic polar codes (NSPCs). Systematic polar codes (SPCs) have been shown to outperform NSPCs with the same encoding and decoding complexity.

Generalized Partially Information Coupled Polar Codes With Arbitrary Coupling Depth and Their Decoding Algorithms

IEEE Access, 2021
We propose generalized partially information coupled (PIC) polar codes and their construction method. In the proposed codes, each code block (CB) shares systematic information bits partially with J adjacent CBs on each side, where J is referred to as the
