Information Theory of Modulation Codes and Waveforms

Abstract The fundamental problem of communication is the conveying of information (which may take several different forms) from a generating source through a communication medium to a desired destination. This conveyance of information, invariably, is achieved by transmitting signals that contain the desired information in some form and that efficiently carry the information through the communication medium. We refer to the process of superimposing an information signal onto another for efficient transmission as modulation . Introduction Analog Modulation Digital Modulation
