Product codes based on binary block codes are considered. The aim is to use simple block codes as component codes in the constructions. Then, by using interleaving, large codes can be obtained. The fundamental aim of the interleaving is to obtain codes with a structure that is suitable for iterative decoding. We present interleaving strategies for iterative (turbo) decoding of block codes. A si...

For any prime number p, positive integers m, k, n satisfying gcd(p, n) = 1 and λ0 ∈ F × pm, we prove that any λ p 0 -constacyclic code of length p n over the finite field Fpm is monomially equivalent to a matrix-product code of a nested sequence of p λ0-constacyclic codes with length n over Fpm.

Software Product Lines (SPLs) refer to some software engineering methods, tools and techniques for creating a collection of similar systems from shared set assets using common means production. This concept is recognized as successful approach reuse in development. Its purpose reduce production costs by reusing existing features managing the variability between different products with respect p...
