Advancements in Communication to Boost Development of Error Correction Technologies.


DUBLIN, Ireland -- Research and Markets (http://www.researchandmarkets.com/reports/c46497) has announced the addition of "Advances in Error Correction Technology (Technical Insights)" to their offering.

This Frost & Sullivan research service titled Advances in Error Correction Technology, provides an overview of error correction theory and technologies along with key drivers, industry challenges, restraints, analysis of error correction codes applied to different applications, and factors that impact code designs. In this study, Frost & Sullivan's expert analysts thoroughly examine the following technologies: forward error correction A communications technique that can correct bad data on the receiving end. Before transmission, the data are processed through an algorithm that adds extra bits for error correction. If the transmitted message is received in error, the correction bits are used to repair it.  technology and related algorithmic developments, technology in implementation, turbo coding, low-density parity check par´i`ty check`

n. 1. (Computers) The act or process of testing whether a byte or other data structure has an even or odd number of bits set to the value of 1; - it is used primarily to detect errors in data, especially in memory
 codes, as well as Reed-Solomon (RS) codes.

Technologies

The following technologies are covered in this research:

- Forward Error Correction Technology: This is an error correction technique, which involves the addition of extra information (also called check bits) to the data.

- Turbo Coding: Introduced in 1993, this is an error correction code used in space and satellite communications because of its high-performance functionality.

- Low-density Parity Check (LDPC LDPC Low-Density Parity Check ) codes: These are linear block codes and are named so because they have a parity check matrix that has few 1s when compared to the number of 0s.

- Reed-Solomon Code (RS): This is a scheme based on the construction of polynomials from the data to be transmitted.

- Cross Interleaved Reed-Solomon Code (CIRC): This is a special type of RS code that can detect and correct all errors on a disc.

- Hamming Code An error correction method that intersperses three check bits at the end of each four data bits. At the receiving station, the check bits are used to detect and correct one-bit errors automatically. : This is a type of error correcting code that does not require any storage.

- Viterbi Decoding: This is also called trellis 1. Trellis - An object-oriented language from the University of Karlsruhe(?) with static type-checking and encapsulation.

Market Overview

Advancements in Communication to Boost Development of Error Correction Technologies

The rise of mobile, wireless, and real-time communications has positively influenced the development of error correction technologies. These technologies have currently positioned themselves as basic enablers of digital communications Transmitting text, voice and video in binary form. See communications.  and storage. Error correction technology ensures reliability and predictability of processes that it controls.

Feedback control systems are greatly enhanced by applying correction techniques to the otherwise unreliable communication channel. In the digital world, the ease in the implementation of various coding algorithms is leading the way for the adoption of convolution codes, as compared to block codes. Forward error correction (FEC See forward error correction.

) techniques in cell phones are likely to offer greater roaming distances in the future.

Correction of Errors Gains Importance as Connected Technologies Evolve

Interframe compression See interframe coding.  techniques in Internet video applications lead to error multiplication. In addition to communication links, the modalities of information storage and delivery have changed over time. The birth of an array of communication modalities has led to the development of algorithms that follow a standardized approach to correcting errors. Moreover, the heterogeneity involved in the core networks has resulted in errors cropping up dynamically. The network design, along with other nodal Having to do with nodes. See node.

 complexities, is necessitating a scheme for the correction of channel errors.

The growth in digital communication channels also necessitates optimal performance of algorithms in their applications. In addition to the research on the development of codes and the implementation of correction schemes, it is necessary to integrate optimization techniques into the algorithms to address performance issues, notes the analyst. The time-sensitive nature and increasing distance between two communication points highlight the importance of updated and advanced error correction technologies.
