Learning Outcomes

This course focuses on the information transmission and signal processing techniques utilized in widely-used communications systems, like mobile communications, wireless LANs, digital TV, and ADSL. These techniques include coding, modulation, filtering, and detection. After the course: * A student can explain the information theoretic foundations of digital communications. She/he recognizes and is able to explain the purpose of source coding, channel coding, and channel capacity for the information transmission task. * A student can recognize and explain the main elements of digital transmission systems and the common digital modulation methods in waveform domain. She/he can also explain the effects of the transmission channel and the electronic modules of the transmission chain on the performance of the transmission system. * A student is able to analyze the transmission link level performance of digital communication systems. She/he recognizes the essential analysis methods and is able to apply them for different communication waveforms. She/he is able to formulate the signal model for a transmission link from a relevant system definition, develop a Matlab model, and simulate its performance. * A student recognizes and is able to explain the main functions of communications transmitters and receivers. She/he can explain the principles of detection theory and apply detection theory to the signal processing functions of communications receivers. * A student can explain the significance and principles of error control coding in digital transmission systems. She/he recognizes the common error control coding methods and knows how the redundancy introduced by the codes can be utilized in the receiver. A student is able to analyze the coding gain at link level.
