ICC 2024 - IEEE International Conference on CommunicationsOrthogonal Time Frequency Space (OTFS) is a framework for communications and active sensing that processes signals in the delay-Doppler (DD) domain. It is informed by 6G propagation environments, where Doppler spreads measured in kHz make it more and more difficult to estimate channels, and the standard model-dependent approach to wireless ...

On the Growth Rate of the Weight Distribution of Irregular Doubly-Generalized LDPC Codes
, 2008 In this paper, an expression for the asymptotic growth rate of the number of small linear-weight codewords of irregular doubly-generalized LDPC (D-GLDPC) codes is derived.

Tanner (3, 23)-Regular QC-LDPC Codes: Cycle Structure and Girth Distribution
IEEE AccessThis paper studies a class of quasi-cyclic LDPC (QC-LDPC) codes, i.e., Tanner (3, 23)-regular QC-LDPC codes of code length $23p$ with $p$ being a prime and $p \equiv 1 (\mathrm {mod} 69)$ .

Optimized puncturing distributions for irregular non-binary LDPC codes
, 2010 In this paper we design non-uniform bit-wise puncturing distributions for irregular non-binary LDPC (NB-LDPC) codes. The puncturing distributions are optimized by minimizing the decoding threshold of the punctured LDPC code, the threshold being computed ...

Generalized Low-Density Parity-Check Coding Aided Multilevel Codes
, 2006 Classic Low-Density Parity-Check (LDPC) codes have recently been used as component codes in Multilevel Coding (MLC) due to their impressive BER performance as well as owing to their flexible coding rates.

, 2012 This paper is concerned with general analysis on the rank and row-redundancy of an array of circulants whose null space defines a QC-LDPC code. Based on the Fourier transform and the properties of conjugacy classes and Hadamard products of matrices, we ...

Research on unequal error protection of irregular LDPC codes
Tongxin xuebao, 2005 An irregular low-density parity-check （LDPC） code with unequal error protection （UEP） property was proposed. A weight-increasing parity-check （WIPC） matrix was constructed.
