WebbDefinition of Shannon Fano Coding. Similar to Huffman coding the Shannon Fano algorithm used to create a uniquely decodable code. It was developed earlier than the Huffman coding algorithm by Claude Shannon and Robert Fano in the year of 1949. This technique also uses the probabilities of the data to encode it. WebbOn compression time aspect, LZ77 is the slowest, approximately 39391,11 ms, while a combination of BWT + MTF + Shannon-Fano performs at approximately 1237,95 ms. This study concluded that the combination of BWT + MTF + Shannon-Fano algorithm performs as the most optimal algorithm in compression time (speed) and compression ratio (size).

WebbStep 2 Determine code length. The code length of each codeword using the formula we will continue to seek: and from this formula called Kraft's inequality, l (1)=1. Doing the same calculation for s2=b, s3=a, s4=c. l2=3, l3=3, l4=4. With this we obtained, d is one digit, b is 3 digits, a is 3 digits, c is 4 digits.
