1. I'm having a hard time understanding error correcting codes. One of the aspects I don't get is how we get d(C) using the Hamming distance. How do we pick u,v?
On a later note, what does the code rate mean? I don't understand the definition in the book.
2. I really like the idea of parity checks and other codes to figure out if the message was sent with an error. It seems like it would be hard to get a perfect message sent every time, so they seem very useful. I've done homework exercises with ISBN codes in other classes, and it's interesting to learn that such a common number that everyone sees uses a parity bit.
