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; - Principle of polynomial interpolation and its applications in communications signal processing.	- Efficient all-digital synchronization algorithms. - Synchronization in CDMA- ja multicarrier systems. - Cramer-Rao bound on the performance of synchronization algorithms. - Realizations structures and design methods for polynomial interpolation.
4.	ADAPTIVE COMPENSATION METHODS: - Use of statistical DSP for compensation of certain non-idealities of the analog parts (I/Q imbalance, nonlinearities).	- More extensive analysis of the used statistical DSP methods and detailed signal models.
