Available in PDF, EPUB and Kindle. Book excerpt: Turbo Code Applications: a journey from a paper to realization presents c- temporary applications of turbo codes in thirteen technical chapters. Each chapter focuses on a particular communication technology utilizing turbo codes, and they are written by experts who have been working in related th areas from around the world. This book is published to celebrate the 10 year anniversary of turbo codes invention by Claude Berrou Alain Glavieux and Punya Thitimajshima (1993-2003). As known for more than a decade, turbo code is the astonishing error control coding scheme which its perf- mance closes to the Shannon’s limit. It has been honored consequently as one of the seventeen great innovations during the ?rst ?fty years of information theory foundation. With the amazing performance compared to that of other existing codes, turbo codes have been adopted into many communication s- tems and incorporated with various modern industrial standards. Numerous research works have been reported from universities and advance companies worldwide. Evidently, it has successfully revolutionized the digital commu- cations. Turbo code and its successors have been applied in most communications startingfromthegroundorterrestrialsystemsofdatastorage,ADSLmodem, and ?ber optic communications. Subsequently, it moves up to the air channel applications by employing to wireless communication systems, and then ?ies up to the space by using in digital video broadcasting and satellite com- nications. Undoubtedly, with the excellent error correction potential, it has been selected to support data transmission in space exploring system as well.

Download or read book Turbo Decoder Architecture for Beyond-4G Applications written by Cheng-Chi Wong and published by Springer Science & Business Media. This book was released on 2013-10-01 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the most recent techniques for turbo decoder implementation, especially for 4G and beyond 4G applications. The authors reveal techniques for the design of high-throughput decoders for future telecommunication systems, enabling designers to reduce hardware cost and shorten processing time. Coverage includes an explanation of VLSI implementation of the turbo decoder, from basic functional units to advanced parallel architecture. The authors discuss both hardware architecture techniques and experimental results, showing the variations in area/throughput/performance with respect to several techniques. This book also illustrates turbo decoders for 3GPP-LTE/LTE-A and IEEE 802.16e/m standards, which provide a low-complexity but high-flexibility circuit structure to support these standards in multiple parallel modes. Moreover, some solutions that can overcome the limitation upon the speedup of parallel architecture by modification to turbo codec are presented here. Compared to the traditional designs, these methods can lead to at most 33% gain in throughput with similar performance and similar cost.

Download or read book High Throughput Iterative Decoders written by Engling Yeo and published by Kluwer Academic Publishers. This book was released on 2007-08-01 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: High Throughput Iterative Decoders: Towards Shannon Bound in VLSI addresses the algorithms and implementations of iterative decoders for error control in communication applications. The iterative codes are based on various concatenated schemes of convolutional codes, also known as turbo codes, and low density parity check (LDPC) codes. The decoding alogirthms are instances of message passing or belief propagation algorithms, which rely on the iterative cooperation between soft-decoding modules known as soft-input-Iterative decoding is a recent advacement in communication theory that is applicable to wireless, wireline, and optical communicatiosn systems. It promises significant advantage in bit-error rate (BER) performance at signal to noise ratios very close to the theoretical capacity bound. However, a direct mapping of the decoding algorithms leads to a multifold increase in the implementation complexity. As deep submicron technology matures, there is a possibility of implementing these applications that were once thought to be too complex to fit onto a single silicon die. We present the architectural and implementation issues related to the VLSI implementation of high throughput iterative decoders. The computational hardware and memory requirements of different competing architectures are discussed. This monograph also introduces reduced complexity modifications of algorithms that provide efficient mapping into architectures and VLSI implementations.

Download or read book Semi-iterative Analogue Turbo Decoding written by Matthieu Arzel and published by . This book was released on 2006 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past decade, telecommunication systems have dramatically grown providing services which require ever more data rate with ever more mobility. To sustain this growth, enhanced and new techniques were implemented in ever more optimised digital circuits. A novel approach could be soon necessary for some of these techniques, due to the limitations of their hardware implementations. Error correction is one of them. It allows to reduce the energy used to send information, but, when implemented on a chip, it is a bottleneck in terms of data throughput and of, paradoxically, power consumption. The analogue iterative decoding could solve this problem. This technique, promising high performance, requires new architectures and codes adapted to the constraints of analogue processing to challenge digital circuits in the field of industrial applications. A novel architecture and a novel turbo decoding algorithm, offering a good compromise between onchip area and data rate, are proposed in this thesis. They pave the way for integrating flexible high-speed analogue turbo decoders dealing with different frame lengths ranging from a few dozen to a few thousand bits. The new architecture and decoding algorithm are applied to a DVB-RCS-like code. The component 8-state decoder used in this new architecture was designed for a 0.25μm BiCMOS process. Dealing with frames made up of 24 double-binary symbols, it is, up to this date, one of the most complex analogue decoders ever designed. Implemented on chip, the circuit was successfully tested at 100Mbit/s while consuming 414mW on a 2.8V analogue core supply. It was shown to provide a bit error rate as close as 0.3dB to the digital one.

Available in PDF, EPUB and Kindle. Book excerpt: When the 50th anniversary of the birth of Information Theory was celebrated at the 1998 IEEE International Symposium on Informa tion Theory in Boston, there was a great deal of reflection on the the year 1993 as a critical year. As the years pass and more perspec tive is gained, it is a fairly safe bet that we will view 1993 as the year when the "early years" of error control coding came to an end. This was the year in which Berrou, Glavieux and Thitimajshima pre sented "Near Shannon Limit Error-Correcting Coding and Decoding: Turbo Codes" at the International Conference on Communications in Geneva. In their presentation, Berrou et al. claimed that a combi nation of parallel concatenation and iterative decoding can provide reliable communications at a signal to noise ratio that is within a few tenths of a dB of the Shannon limit. Nearly fifty years of striving to achieve the promise of Shannon's noisy channel coding theorem had come to an end. The implications of this result were immediately apparent to all -coding gains on the order of 10 dB could be used to dramatically extend the range of communication receivers, increase data rates and services, or substantially reduce transmitter power levels. The 1993 ICC paper set in motion several research efforts that have permanently changed the way we look at error control coding.
