Modulation coding, to limit the number of consecutive zeroes in a data stream, is essential in digital magnetic recording/playback systems. Additionally, such sys­ tems require error correction coding to ensure that the decoded output matches the recorder input, even if noise is present. Typically these two coding steps have been performed independently, although various methods of combining th...

Error-correcting or error-detecting codes have been used in the computer industry to increase reliability, reduce service costs, and maintain data integrity. The single-byte error-correcting and double-byte error-detecting (SbEC-DbED) codes have been successfully used in computer memory subsystems. There are many methods to construct double-byte error-correcting (DbEC) codes. In the present pap...

Two construction methods for t error correcting constant weight codes are developed. Both of these methods are improvements over the existing codes. One construction is recursive, which is based on the observation that a 2t error correcting code can be built by concatenating two t error correcting codes. This results in the reduction of code word length for higher t values. The other constructi...

VLSI Architectures for Modern Error-Correcting Codes CRC Press Book. Reed-Solomon (RS) and Bose-Chaudhuri-Hocquenghem (BCH) codes, and binary. An important class of multipleerror-correcting linear cyclic codes is the class of BCH codes. In fact, BCH code is a generalization of the cyclic Hamming codes. Error correction codes (ECCs) are deployed in digital communication systems to tion 4 recalls...

This paper gives two lossless speech compression schemes Hamming correction codes compressor (HCCC) and Systematic Linear Block Code Compressor (SLBC) based on error correcting Hamming code and systematic linear block codes respectively. Hamming codes are a family of linear errorcorrecting codes that can detect up to two-bit errors or correct one-bit errors. Systematic linear block code is any ...

Turbo codes are one of the most efficient error correcting code which approaches the Shannon limit. However the major drawback of turbo codes is its high latency due to its iterative decoding process. The high throughput in turbo decoder can be achieved by parallelizing several Soft Input Soft Output(SISO) units together. In this way, multiple SISO decoders work

Multiclass learning problems involve nding a deenition for an unknown function f (x) whose range is a discrete set containing k > 2 values (i.e., k \classes"). The deenition is acquired by studying collections of training examples of the form hx i ; f (x i)i. Existing approaches to multiclass learning problems include direct application of multiclass algorithms such as the decision-tree algorit...
