BCH Encoder Labview

Hello,

i have a problem. I need a Channel Coding for a 56 Bit Bitstream. The code is a modified BCH-Code (63,56. My generator polynom is x^7+x^6+x^2+x^0.

I have the NI Modulation Toolkit, but it dosnt help. In the MT BHC Encoder.vi i cant adjust the generatorpolynom and use the (63,56). 

Has anyone an idee or an example for me? 

thanks

Hi,

the MT BHC.vi uses the order m to choose a polynomial from a table in a subvi inside MT BHC.vi.

From outside it is not possible to specify a custom polynomial, so you could try to change is inside, but 

I cannot tell what exactly happens there.

Hello,

i had tryed to change it inside but it doesn't work. The polynom will change automatically.I think i can't use thisVI.
