Objectives
The goal is to understand the key RF-functionalities and related performance issues when designing the analog and digital signal processing blocks for communications receivers and transmitters. The course introduces also certain DSP algorithms that are interesting when the RF functionalities are increasingly desired to be implemented with digital signal processing.

Content
Content Core content Complementary knowledge Specialist knowledge
1. Receiver Architectures
- Basic architectures of communications receivers: superheterodyne, direct-conversion, low-IF.
- Effects of non-idealities in practical analog implementations: I/Q imbalance, nonlinearities, noise, phase noise, spurious responses. System calculation principles.
- The significance of RF specifications of mobile communication systems on the specs of the signal processing blocks.
- Flexible multistandard receiver structures and flexible spectrum use; software defined radio and cognitive radio concepts. 		      
2. Multirate DSP
- Principles of multirate signal processing and extensions to bandpass and complex (I/Q) cases.
- Review of efficient realization structures; polyphase structure, CIC filters.
- Continuous-time, discrete-time, and multirate signal processing in case of complex (I/Q) and bandpass signals.
- Sampling of bandpass signals and I/Q signals. Sampling and ADC requirements regarding resolution and sampling jitter.
- Efficient DSP algorithms for communications receivers. 		 Delta-sigma A/D-conversion principle.    
3. Synchronization
- Requirements and methods for carrier and symbol synchronization.
- Maximum Likelihood estimation theory in synchronization.
- All-digital synchronization principles.
