Advances in Error Correction Technology (Technical Insights)
Frost & Sullivan, March 2006
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 technology and related algorithmic developments, technology in implementation, turbo coding, low-density parity check codes, as well as Reed-Solomon (RS) codes.
Market Sectors
Expert Frost & Sullivan analysts thoroughly examine the following technology sectors in this research:
-Digital communication and digital storage
-Voice over Internet Protocol (VoIP)
-Space and satellite communication
-Modems
-Wireless communication
-CD-ROM
-Memory devices
-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.
