摘 要：Digital communication is the foundation of modern telecommunications. Basically, it is, an evolution of analog communication that explores the advantages of the information in a digital format. For this reason, differently from analog communication systems, digital systems have to identify, at the receiver, only a finite number of possible transmit waveforms from the received signal and, consequently, they are much more powerful than any analog system.
