  2. Multiple-input multiple-output (MIMO) and Multiple-input single-output (MISO) radio channel modeling;
  3. Downlink and Uplink mmWave communications;
  4. Channel Estimation (LOS and NLOS) and Performance Analysis.

 

Lab projects will include if necessary

- A review of pulsed radars and a brief introduction to frequency-modulated continuous wave (FMCW) radars.

- A review of goodness of fit techniques.

- An introduction to positioning techniques.

- An Introduction to modeling and simulation of wireless communication systems.

 

 

Overview.

This is a laboratory-based course intended to show the application of statistical signal processing techniques to the design and the analysis of wireless systems and radars.

Learning Outcomes.

Knowledge and understanding

After the course the student should know the tools necessary 1) to fit a statistical model to data and 2) to design algorithms to retrieve information chosen according to the adopted model.

Applying knowledge and understanding

After the course the student should be able to

*fit a statistical model to data in terms of first order distribution and autocorrelation function;

*solve detection and estimation problems for the selected applications.

*Evaluate the performance parameters and discuss complexity issues associated with different solutions.

Making judgements

Students should acquire the ability to compare pros and cons of different approaches to the solution of a specific problem (laboratory experiences).

Communication

The ability to communicate on technical topics should be acquired by reporting on laboratory experiences.

Learning skills

Laboratory experiences will require elaborating on techniques introduced in previous courses, also with the help of selected readings suggested by the instructor. Identifying solutions to non trivial problems will be  important to be ready for autonomous lifelong learning.

Lectures and computer/experimental projects. Most of the activity is performed in the laboratory where students can setup experiments regarding radar signal processing and wireless transmissions in Matlab and/or using Software Defined Radio (SDR) platforms. To attend the course, the student is NOT required to have knowledge of these tools in advance

The exam will be composed of an oral part (30%) and a practical part (70%) where some modifications to the software and experiments developed during the course will be required; the objective of the practical part is not to focus on programming skills, but to verify the knowledge level of the discussed topics.
