WebJan 6, 2024 · Look for known inequalities. Proving inequalities, you often have to introduce one or more additional terms that fall between the two you’re already looking at. This often means taking away or adding something, such that a third term slides in. Always check your textbook for inequalities you’re supposed to know and see if any of them seem ...

Based on this result, he was able to prove that the expected length of a uniquely decodable code for a random variable X is not smaller than its entropy, E[l(X)] ≤ H(X). This represents a strong converse result in coding theory. gc5shgxls01
