Function:
Calculate the parity of frames using H-matrix multiplication.
By clicking the H-matrix setup field a drop-down list appears. Enter the matrix size in the Rows and
Columns fields, then proceed to fill in logical ‘1’ in the appropriate positions of the matrix by left-clicking
the position. A context label indicates the cursor position.
The function returns Number of code words processed in the Calculation category and in a document
window a list of the analyzed frames and the calculated parity bits in bit notation and parity marked as
Parity o.k. or Parity error.
Parity from polynomial
In: Bit stream
Out: Bit stream
Function:
Calculate the parity of frames by generating an H-matrix from the corresponding cyclic linear block code
generator polynomial. The bit stream is then multiplied by the generated H-matrix.
The parameters listed below configure the function:
Parameter Description Value
Data length in code word Number of data bits in code word

Generator polynomial (standard
format)
Use the drop-list to open a window for entering the
generator polynomial
