Topics in Coding Theory: 1. The A(,s)(n,d) Problem in The Plotkin Region. 2. Number of Information Symbols in a Bch Code
… The problem is to finding the maximum number of codewords in a code on an alphabet with s symbols that has length n and minimum Hamming distance d. The Plotkin Region is the set of n and d such that sd > t(s - 1)n. We define Generalized Hadamard matrices, using a notion of orthogonality over a …

Álgebra de corpos finitos aplicada à teoria da codificação: estudo do codificador BCH.
… Theory, through the study of error correcting codes and a sepcial class denoted BCH. The BCH code building uses algebraic structure of finite fields and are characterized by operations on polynomials. In order to understand the operation of the BCH codes, we will make a brief introduction to …

Study of Modulation and Error Control Coding in Thick Film Digital Magnetic Recording
… application of Modulation and Error Correction codes to Digitally Recorded Magnetic Data.<br/><br/>The effects of these coding schemes were measured against bitshift errors which are induced by different Non Clockloss Error Mechanisms. These Error mechanisms are Noise and Inter Symbol …

Contributions to the decoding of linear codes over Z4
… and soft decision decoding techniques for linear codes over Z4, all of which, offer substantial coding gains over classical algebraic decoding. We focus only on codes which are free, i.e., (n, k, d) linear codes whose canonical images over GF(2) are (n, k) linear codes of the same minimum distance …
