FEC code: BCH with p(x)=x^5+x^2+1, t=2

In this case, the table I used was from [Wolfram MathWorld](http://mathworld.wolfram.com/PrimitivePolynomial.html), but similar tables are found in many a book on encoding. Once you have the primitive polynomial, you can...

FEC code: BCH with p(x)=x^5+x^2+1, t=2

> Mm! I also find them tons more eyeball-friendly when in the debugging stage and staring at a logic analyzer. Glad to hear that they're common then. They are less...

FEC code: BCH with p(x)=x^5+x^2+1, t=2

> Entirely possible and I hadn't thought of that. It's not likely that it's an opcode since the "commands" are sent from the GameCube to the controller, and the controller...

FEC code: BCH with p(x)=x^5+x^2+1, t=2

Did some simulations. Even with the non-systematic coding and an inner interleaver, 16% of incorrigible three-bit errors sneak past the magic number test. However, the unprotected CRC also causes 34%...

FEC code: BCH with p(x)=x^5+x^2+1, t=2

Not done the sim yet, but I am fairly certain that the false negative rate will be immeasurably low. I actually managed to speed up the non-systematic calculation quite a...
