If you want to write code for a modem, this is your text. digital communication john r. barry pdf

Most textbooks treat wireless fading channels and wired (copper/fiber) channels as separate universes. Barry demonstrates that the underlying signal processing principles—equalization, channel coding, and synchronization—are unified. This saves the student from learning two divergent frameworks. Unlike older texts that treat analog and digital
