A First Look at Shannon's Communication Theory
In his landmark 1948 paper[1], Claude Shannon developed a general model for communication systems, as well as a framework for analyzing these systems. The model has three components: (1) the sender or source, (2) the channel, and (3) the receiver or sink. The model also includes the transmitter that encodes the message into a signal, the receiver, for decoding the signal back into a message, as well the noise of the channel, as shown in Fig. 1.
In Shannon's discrete model, the source provides a stream of symbols from a finite alphabet, , which are then encoded. The code is sent through the channel, which could be corrupted by noise, and when the code reaches the other end, it is decoded by the receiver, and then the sink extracts information from the steam of symbols.
