Binary Cyclic Encoder
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 polynomial, namely,
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 Communications Toolbox™
For information about the data types each block port supports, see the Supported Data Type table on this page.
- Codeword length N
The codeword length, which is also the output vector length.
- Message length K, or generator polynomial
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.
