Characteristics of a digital communications system. Characteristics of telecommunications channels. Mathematical models of telecommunications channels. Coding of discrete information sources: PCM, differential PCM, adaptive PCM. Binary representation of signals: PAM, PSK, QAM, FSK, CPFSK, MSK. Spectral characteristics of digitally modulated signals. Optimal receiver for white Gaussian noise. Bit error rate performance of the optimal receiver for different digital modulation techniques. Synchronization. Inter-symbol interference. Orthogonal Frequency Division Multiplexing (OFDM). Multiple Input/Multiple Output (MIMO) transmission.
The main goal of the course is to familiarize the students with the theory of modern digital communications and to deepen their knowledge on the philosophy of digital communication systems. The course allows the students to develop their skills in performance evaluation of communication systems using Matlab and Simulink and to understand various relevant performance metrics. Finally, by simulating modern communication systems (digital modulaton, coding, OFDM, MIMO), the student will understand their mode of operation.
