WebbHuffman and Shannon- Fano are two compression algorithms have same ways to work, but both produced a different performance. The test results concluded that the Shannon-Fano performance has a percentage of 1,56% lower than Huffman. This problem can be solved by adding a reversible transformation algorithm to the data source. Webb26 aug. 2016 · Shannon's coding theorem. Roughly speaking, if channel capacity is C, then we can send bits at a rate slightly less than C with an encoding scheme that will reduce probability of a decoding error to any desired level. Proof is nonconstructive. Q+A Exercises Which of the following codes are prefix free? Uniquely decodable?
