-
- I am trying to develop a communication protocol which uses error correction.
- Because of hardware constraints, a 32-bit message length is best. Of this
- I need at least 24 bits of data, leaving me with 8 checksum bits.
-
- I want to use a code that corrects at least 2 bits of error per message.
- I've looked in a few texts and determined that some sort of BCH code will
- do this. However, all of the references that I ahve found have been dry,
- mathematical texts that give me no idea whatsoever how to effeciently
- implement an algorithm to do this.
-
- Any suggestions from the net, either algorithms or references?
-
- Thank you for any assistance you can provide.
