Keywords: optimal code | communication channel | entropy | information | transition functions

This paper aims to present the methods of achieving an optimal encoding in the data communication channels. After a short description of the communication channel and of the data communication channel types, follow briefly a few notions of the data channel enthropy, information, transinformation, with their properties, definitions and mathematical relations connecting them. Chapter 2 presents the concept of optimal code, following a detailed description (using two suggestive examples) of the two main methods used to obtain an optimal code: Shannon-Fano and Huffman.
