The students are able to design digital adaptive systems. Further, they can understand different digital modulation techniques and digital communication systems.
They can design basic building blocks that are necessary in transmission systems (e.g. equalizers, echo compensation, synchronization, clock recovery, ...).
Digital Signal Processing.
The lecture deals with fundamentals of digital communications and basic building blocks.
• Adaptive Systems
• Modelling of systems based on Least -Mean-Squares-Algorithmus (LMS)
• Modulation Techniques
o Pulse-Amplitude-Modulation (PAM)
o Quadrature-Amplitude-Modulation (QAM)
o Discrete Multi Tone (DMT)
• Communication Systems
o Time Division Multiplex
o Frequency Division Multiplex
o Frequency Overlap
o Cross-Talk (NEXT, FEXT)
• Basic Building blocks of a transmission system
- Linear Equalizer
- Decision Feedback Equalizer
o Digital Echo Compensator
o Clock recovery (PLL, digital synchronization)
•Applications (ADSL, VDSL)
