Regarding the confusion in the two different codes being referred to by the same name, Krajči et al. write: Around 1948, both Claude E. Shannon (1948) and Robert M. Fano (1949) independently proposed two different source coding algorithms for an efficient description of a discrete memoryless source. Unfortunately, in spite of being different, both schemes became known under the same … Regarding the confusion in the two different codes being referred to by the same name, Krajči et al. write: Around 1948, both Claude E.

For the example in Shannon–Fano–Elias coding I changed the coefficient to 1/3. I obtained this code: 000, 011, 1010, 110. It's still a prefix code. – user263485 Dec 22, 2013 at 18:31 Might be better suited to CompSci.SE. – dmckee --- ex-moderator kitten Dec 23, 2013 at 1:12 Add a … chris alana bachelor in paradise
