Web13 aug. 2024 · As vonbrand noted, Huffman coding falls back to binary encoding if all frequencies are equal. For longest code length, this happens if the frequencies are Fibonacci numbers. For worst compression rate compared to the entropy, this happens with an alphabet of two symbols where p 0 = ε and p 1 = 1 − ε.

Web6 dec. 2024 · Huffman encoding optimizes the message length, given the frequency table. What you do with the frequency table is up to you. Applications for very short messages often assume a static frequency table that both the transmitter and receiver know in advance, so it doesn't have to be transmitted.
