A digital communication system conveys discrete-time, discrete-valued information across a physical channel. The purpose of any communication system is to transport an information-bearing signal from a source to a user destination via a communication channel. Hence, Digital Communication involves the transmission of information from a source that generates the information to one or more destinations. Information sources might include audio, video, text, or data. They might be continuous-time (analog) signals (audio, images) or digital (discrete-time, discrete-valued). Digital techniques refer to any process, which is accomplished using discrete units. The course assumes a previous exposure to Communication Principles, Fourier Transforms, Signals and Systems, Probability and Random Processes. Topics covered include but not limited to: Elements of a Digital Communication System, Signal Analysis, Probability and Random Processes, Information Theory and Channel Capacity, Analog Vs. Digital Communication System, Coding Techniques, Pulse Modulation, Data Transmission and Detection, Spread Spectrum Techniques, Fading Channels, Multiple-Antenna Systems. Engr. G.K. Ijemaru
