Polar Codes: Finite Length Implementation, Error Correlations and Multilevel Modulation

Shannon, in his seminal work, formalized the transmission of data over a communication channel and determined its fundamental limits. He characterized the relation between communication rate and error probability and showed that as long as the communicatio ...

A 15.8 pJ/bit/iter quasi-cyclic LDPC decoder for IEEE 802.11n in 90 nm CMOS

Andreas Peter Burg, Pascal Andreas Meinerzhagen, Christoph Studer

We present a low-power quasi-cyclic (QC) low density parity check (LDPC) decoder that meets the throughput requirements of the highest-rate (600 Mbps) modes of the IEEE 802.11n WLAN standard. The design is based on the layered offset-min-sum algorithm and ...

VLSI Implementation of a Low-Complexity LLL Lattice Reduction Algorithm for MIMO Detection

Andreas Peter Burg, Christoph Studer

Lattice-reduction (LR)-aided successive interference cancellation (SIC) is able to achieve close-to optimum error-rate performance for data detection in multiple-input multiple-output (MIMO) wireless communication systems. In this work, we propose a hardwa ...

Selective Redundancy-Based Design Techniques for the Minimization of Local Delay Variations

Alexandre Schmid, Yusuf Leblebici, Milos Stanisavljevic

In this paper a novel approach to optimize digital integrated circuits yield with regards to speed and area/power for aggressive scaling technologies is presented. The technique is intended to reduce the effects of intra-die variations using redundancy app ...

Theory and applications of Raptor codes

Mohammad Amin Shokrollahi

Digital media have become an integral part of modern lives. Whether surfing the web, making a wireless phone call, watching satellite TV, or listening to digital music, a large part of our professional and leisure time is filled with all things digital. Th ...

Robust Image Transmission Based on Product-Code Optimization for Determinate State LDPC Decoding

Nikolaos Thomos

We propose a novel scheme for error resilient image transmission. The proposed scheme employs a product coder consisting of LDPC codes and RS codes in order to deal effectively with bit errors. The efficiency of the proposed scheme is based on the exploita ...

Asymptotic and finite-length optimization of LDPC codes

Abdelaziz Amraoui

This thesis addresses the problem of information transmission over noisy channels. In 1993, Berrou, Glavieux and Thitimajshima discovered Turbo-codes. These codes made it possible to achieve a very good performance at low decoding complexity. In hindsight, ...

Wireless Image Transmission Using Turbo Codes and Optimal Unequal Error Protection

Nikolaos Thomos

A novel image transmission scheme is proposed for the communication of SPIHT image streams over wireless channels. The proposed scheme employs turbo codes and Reed-Solomon codes in order to deal effectively with burst errors. An algorithm for the optimal u ...
