(computer science)
A code, such as a binary code, that changes only in one digit when going from one number to the number immediately following, and in that digit by only one unit.

If C is a cyclic code of length n, then C has a generator polynomial g(x) which is a divisor of [x.
Abstract In this paper, we use 4-cyclotomic cosets of modulo n and generator polynomials to describe quaternary simple-root cyclic codes of length n = 85.
So it is natural to construct quantum error-correcting codes from quaternary cyclic codes.
In particular, Jacques Wolfmann studied within this framework the notion of cyclic code (code which is invariant by the action of the cyclic group of permutations: particular case of affine groups).
n] is a linear affine-invariant codes then C is a linear cyclic code.
We prove b) and c) by using the definition of affine-invariant and the fact of if C is a linear cyclic code of length n over [[?
n]) suffices to see if a linear cyclic code of length odd is affine-invariant or not.
The essential quality of a cyclic code is that any cyclic permutation or end-around shift of a code word results in another code word.

By combining filter, Viterbi and cyclic code co-processors with an 80 MHz DSP56300 core, the DSP56305 performs all the signal processing required by a single radio carrier, executing functions that have previously required up to five separate DSPs.
