Study of Encoders with Data Transmission Binary Channels Without Interference. Simulation of the Encoder Functioning Using the Electronic Workbench Software

摘要

This paper aims to create and test a data transmission channel coder for binary channels with no interferences or with insignificant disturbances. These are the simplest types of data channels known in the theory of information transmission and encoding. We intend to test the encoder using the Electronic Workbench 5.12 software with simple graphical interface and enough libraries to simulate and test the functioning of most analogical and digital electronic circuits. We will use a message source that generates four distinct types of messages which occur with probabilities as negative powers of two, being encoded through four distinct code words; words which build a four-sized prefix code. It is very important because, once this type of encoder is built we can make generalizations for the probability distributions of the source S with n message type {formula}, {formula} being the probability of the least likely message in a sequence of n messages generated by the source.
