Figure 1.1 illustrates discrete data transmission‚ which is the transmission of one message from a finite set of messages through a communication channel. A message sender at the transmitter communicates with a message receiver. The sender selects one message from the finite set‚ and the transmitter sends a corresponding signal (or “waveform”) that represents this message through the communication channel. The receiver decides the message sent by observing the channel output. Successive transmission
