Design of Rate-Compatible Parallel Concatenated Punctured Polar Codes for IR-HARQ Transmission Schemes

open access: yesEntropy, 2017
In this paper, we propose a rate-compatible (RC) parallel concatenated punctured polar (PCPP) codes for incremental redundancy hybrid automatic repeat request (IR-HARQ) transmission schemes, which can transmit multiple data blocks over a time-varying ...

Exit chart analysis of parallel data convolutional codes [PDF]

open access: yes, 2005
We recently proposed a new class of turbo-like codes called parallel data convolutional codes (PDCCs). The distinct characteristics of PDCCs include parallel data input bits and a self-iterative soft-in/soft-out a posteriori probability(APP) decoder. In

Low-Latency Adaptive Ordered Statistic Decoding of Polar Codes

open access: yesIEEE Access, 2019
Deploying polar codes in ultra-reliable low-latency communication (URLLC) is of critical importance and is currently receiving tremendous attention in both academia and industry. However, most of the state of the art polar codes decoders like progressive

Turbo Decoding and Detection for Wireless Applications [PDF]

open access: yes, 2007
A historical perspective of turbo coding and turbo transceivers inspired by the generic turbo principles is provided, as it evolved from Shannon’s visionary predictions.

Coding theorems for turbo code ensembles [PDF]

open access: yes, 2002
This paper is devoted to a Shannon-theoretic study of turbo codes. We prove that ensembles of parallel and serial turbo codes are "good" in the following sense.

Good Concatenated Code Ensembles for the Binary Erasure Channel

open access: yes, 2009
In this work, we give good concatenated code ensembles for the binary erasure channel (BEC). In particular, we consider repeat multiple-accumulate (RMA) code ensembles formed by the serial concatenation of a repetition code with multiple accumulators ...

On Maximum Contention-Free Interleavers and Permutation Polynomials over Integer Rings [PDF]

open access: yes, 2005
An interleaver is a critical component for the channel coding performance of turbo codes. Algebraic constructions are of particular interest because they admit analytical designs and simple, practical hardware implementation. Contention-free interleavers

A New Class of Braided Block Codes Constructed by Convolutional Interleavers

open access: yesMathematics
Parallel Concatenated Block (PCB) codes are conventionally represented as high-rate codes with low error correcting capability. To form a reliable and outstanding code, this paper presents a modification on the structure of PCB codes, which is ...

Self-concatenated code design and its application in power-efficient cooperative communications

open access: yes, 2012
In this tutorial, we have focused on the design of binary self-concatenated coding schemes with the help of EXtrinsic Information Transfer (EXIT) charts and Union bound analysis.
