Huffman coding equal probability
WebE ciency of code 1 = 1:4568 1:6 = 91:05% E ciency of code 2 = 1:4568 1:465 = 99:44% Code 2 represents a signi cant improvement, because it eliminates the ‘zero’ state of code 1 which has a probability well above 0.5 . 6. While we cover in 3F1 and 4F5 the application of Shannon’s theory to Webcode for a given distribution. However, the best prefix code for a general source code distribution is the Huffman Code. Huffman Algorithm: 1- Find 2 symbols with the smallest probability and then merge them to create a new “node" and treat it as a new symbol. 2- Then merge the next 2 symbols with the smallest probability to create a new “node"
