Hey guys,
I am just wondering, what are the ways to implement decoding via hardware? I have an input of c(x) - encoded message - and g(x) - polynomial generator.
I know that by dividing c(x) by g(x), and having no reminder mean that there was no error. I am fine in doing this either by hand or in C, but I can't seem to grasp it in hardware.
What I was thinking was to use a shift register to shift g(x) and XOR specific parts with an input, but that is way to complicated, plus it would work only for a given example! I did some googling, and came across LFSR, but it seems to be very similar to what I was thinking of doing.
Can anyone help me out? Any hits or tips? Any ideas?
Thanks a lot!
