Create systematic cyclic code from binary vector data
Block sublibrary of Error Detection and Correction
The Binary Cyclic Encoder block creates a systematic cyclic code with message length K and codeword length N.
This block accepts a column vector input signal containing K elements. The output signal is a column vector containing N elements.
You can determine the systematic cyclic coding scheme in one of two ways:
To create an [N,K] code, enter N and K as the first and second dialog
parameters, respectively. The block computes an appropriate generator
To create a code with codeword length N and a particular
degree-(N-K) binary generator polynomial, enter
N as the first parameter and a polynomial character
vector or a binary vector as the second parameter. The vector
represents the generator polynomial by listing its coefficients in order of
ascending exponents. You can create cyclic generator polynomials using the

The codeword length, which is also the output vector length.
Either the message length, which is also the input vector length, a polynomial character vector, or a binary vector that represents the generator polynomial for the code.
