Cyclic codes can be used to correct errors, like Hamming codes as a cyclic codes can be used for correcting single error.
22.
Any cyclic code can be converted to quasi-cyclic codes by dropping every b th symbol where b is a factor of n.

Although this definition is sufficient to describe what a burst error is, the majority of the tools developed for burst error correction rely on cyclic codes.
25.
To convert ( n, k ) cyclic code to ( n-b, k-b ) shortened code, set b symbols to zero and drop them from each codeword.

Before delving into the details of cyclic codes first we will discuss quasi-cyclic and shortened codes which are closely related to the cyclic codes and they all can be converted into each other.

An [ n, k ] linear code is called a " proper shortened cyclic code " if it can be obtained by deleting b positions from an ( n + b, k + b ) cyclic code.

So, cyclic codes are vectors in the field GF ( q ) and the spectrum given by its inverse fourier transform is over the field GF ( q ^ m ) and are constrained to be zero at certain components.
