WebbThe Shannon noiseless coding theorem have multiple ways by which the errors can be reduced while the . Shannon noisy coding theorem do not have any specific way to overcome the errors. So the sub-optimal codes like convolution codes are used to overcome the errors. The Shannon noisy coding theorem can be used for various
WebbClaude Shannon established the two core results of classical information theory in his landmark 1948 paper. The two central problems that he solved were: 1. How much can a message be compressed; i.e., how redundant is the information? This question is answered by the “source coding theorem,” also called the “noiseless coding theorem.” 2. WebbThe Shannon Noiseless Source Coding theorem states that the average number of binary symbols per source output can be made to approach the entropy of a source. In another words, the source efficiency can be made to approach unity by means of source coding. For sources with equal symbol probabilities, and/or statistically independent to each other,
