Full Diversity Low-Density Parity-Check (LDPC) Codes for Block-Fading Channel
2023 International Conference on Electronics, Information, and Communication (ICEIC), 2023Refereed/Peer-reviewed The main goal of this paper is to design full-diversity and outage achieving LDPC codes over block-fading channels under message passing decoding. This paper presents the derivation of the necessary properties of full diversity LDPC codes under message passing decoding over block-fading channel.

Low-density parity-check (LDPC) coded OFDM systems
IEEE 54th Vehicular Technology Conference. VTC Fall 2001. Proceedings (Cat. No.01CH37211), 2002Orthogonal frequency division multiplexing (OFDM) is a very attractive technique for high-bit-rate data transmission in a multipath fading environment that causes intersymbol interference (ISI). There are many error-correcting codes applied to OFDM, convolutional codes, Reed-Solomon codes, turbo codes, and so on.

Low-density parity-check code (LDPC) schemes with BICM
International Conference on Communication Technology Proceedings, 2003. ICCT 2003., 2004LDPC codes are serious opponent of turbo codes. This paper presents LDPC schemes using bit-interleaving coded modulation (BICM), which can increase the spectral efficiency two or three times with little loss of power efficiency. And the decoding complexity is also addressed in this paper.

Low density parity check (LDPC) codes for optical data storage
International Symposium on Optical Memory and Optical Data Storage Topical Meeting, 2003Low-density parity check (LDPC codes, first introduced by Gallager (1962), are error-correcting codes based on very sparse parity check matrices. Recently, in the wake of excellent performance of turbo codes, LDPC codes were rediscovered as another category of random codes approaching the Shannon capacity limit with practical decoding complexity ...

Performance of low-density parity-check (LDPC) coded OFDM systems
2002 IEEE International Conference on Communications. Conference Proceedings. ICC 2002 (Cat. No.02CH37333), 2003Orthogonal frequency division multiplexing (OFDM) is a very attractive technique for high-bit-rate data transmission in multipath environments. Many error-correcting codes have been applied to OFDM. Recently, LDPC codes have attracted much attention. The performance of LDPC codes is very close to the Shannon limit, with practical decoding complexity ...

Bootstrapped Iterative Decoding Algorithms for Low Density Parity Check (LDPC) Codes
2010 Fifth International Conference on Systems and Networks Communications, 2010Reliability ratio based weighted bit-flipping algorithm is one of the best hard decision decoding algorithms in performance. Recently several modifications are done to this technique either to improve performance or to lower the complexity. The implementation efficient reliability ratio based weighted bit-flipping is developed targeting decreasing ...

Low-Density Parity-Check (LDPC) Coded Framelet Transform-Based OFDM System
Proceedings of the International Conference on Imaging, Signal Processing and Communication, 2017Framelet Transform-based OFDM (FT-OFDM) was proposed recently as an alternative to traditional Fast Fourier Transform-based OFDM (FFT-OFDM). By using the Framelet Transform, the spectral containment of the channels will be more efficient, since it does not use Cyclic Prefix (CP) that usually used in the traditional model.

Optimized low-density parity-check (LDPC) codes for bandwidth efficient modulation
2003 IEEE 58th Vehicular Technology Conference. VTC 2003-Fall (IEEE Cat. No.03CH37484), 2003In this paper, we implement an efficient MLC/PDL system for AWGN channels. In terms of the tradeoff between hardware implementation and system performance, proposed LDPC code is optimized by Gaussian approximation (GA) according to the rate of each level assigned by the capacity rule and chosen as the component code.
