Course Contents
The Wireless Communications course provides an overview of the essential aspects of the physical layer as well as transmission system design aspects of generic wireless communications systems. The following aspects will be covered in the course:

1. Radio propagation
* Review of radio propagation, link-budget model
* Introduction of multipath propagation
- time domain : rms-delay spread, signal dispersion, inter-symbol interference
- frequency domain: frequency selectivity, coherence bandwidth
* Path-loss model
* Channel models
- stochastic channel models,
- model parameters for some characteristic indoor environments
- how to use a stochastic model

2. Modulation techniques
* Higher order modulation schemes (review): BPSK, QPSK, M-PSK, M-FSk, M-QAM
* Direct Sequence Spread Spectrum (DS-SS)
* Orthogonal Frequency Division Multiplexing (OFDM)

3. Diversity to increase robustness against transmission anomalies
* Frequency/time/space diversity
- antenna diversity: selection diversity, maximal ratio combining

4. Channel Coding
* Characterization of error types, and basics of error control coding
* Code design: trade-off between efficiency, reliability, complexity/delay
* Block & convolutional codes
* Viterbi decoding
* Puncturing
* Interleaving

5. Power-Bandwidth Trade-Off
* M-ary Modulation
* Bandwidth Efficiency
* System Design Examples

6. Cellular System Design
* Tele-traffic Engineering, Erlang B&C formulas
* Frequency re-use
* Co-channel interference
* Sectoring

7. Network Coding
* New communication paradigm
* Encoding and decoding procedures

Study Goals
The student has obtained insight in the different relevant aspects of wireless mobile communications systems related to the Physical layer: propagation, modulation, coding, diversity, and is able to explain the relations between the different issues and trade-offs that can be made when designing a wireless communication system.
The main goal of this course is to extend the analytical knowledge obtained in the basic (telecommunication) courses to the synthetic skills of systems engineering and the design of means of digital transmission, used in modern public and business networks. Furthermore, the student becomes familiar with the basics and applicability of some of the latest telecommunication technologies (see course contents).
When facing a (simplified) real-world telecommunications problem, the student must be capable to act as a consultant, giving recommendations on the most suitable technologies solving the given problem.
The obtained knowledge and skills have to be demonstrated in a written exam in the format of a system design problem.
Education Method
Lectures, instruction lectures and homework exercises.
