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) 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: This is a type of error correcting code that does not require any storage.
Viterbi Decoding: This is also called trellis decoding and is a common technique used to decode a convolution code.

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 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) 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 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 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."
