Overview:
Modern communication systems apply digital transmission methods to overcome the impairments caused by an unreliable physical medium. In this course, the most important characteristics of physical communication channels are discussed, concentrating on time and frequency selective fading. Physical layer technologies to digitize signals, and to transmit digital information over a physical medium, are discussed and analyzed. Digital modulation techniques for rapidly and slowly fading channels are discussed (differential vs. non-differential modulation). Equalization techniques and modulation methods (CDMA, OFDM) for wide band channels (i.e. frequency selective fading) are discussed. Diversity combining methods to improve perofmenace over fading channels are considered. Most of the content of the course is geared towards wireless communication.
After the course, the student understands the fundamental characteristics of physical communication channels, how they affect communication over a channel, and how the typical characteristics of a channel should be taken into account when designing the physical layer of a communication system for the channel. The student understands signal space representations of digitally modulated signals, and is able to analyze the performance of digitally modulated signals in fading channels, with and without diversity
