WebMar 10, 2024 · The Hamming(7,4) code may be written as a cyclic code over GF(2) with generator [math]\displaystyle{ 1+x+x^3 }[/math]. In fact, any binary Hamming code of the form Ham(r, 2) is equivalent to a cyclic code, and any Hamming code of the form Ham(r,q) with r and q-1 relatively prime is also equivalent to a cyclic code.

WebBut for some codes this decoding problem can be solved efficiently. If such an algorithm is available for a code C, we say that C has a decoder. 2.1 Quasi-Cyclic codes A quasi-cyclic code (QCC) is a block linear code which is a simple generalisation of the cyclic code. It is such that any cyclic shift of any codeword by m symbols gives another ... WebRegarding quasi-cyclic codes as certain polynomial matrices, we show that all reversible quasi-cyclic codes are decomposed into reversible linear codes of shorter lengths …
