In former times, communication systems were typically designed based on either mathematical analysis or empirically laboratory measurements. Due to the increasing complexity of modern communication systems, analytical solutions in many cases do not exist, while lab experiments demand the availability of many expensive devices, in order to be able to build the complete system. A third way to investigate a communication system is to simulate it with the help of a computer. Due to the reasons mentioned above, simulation tools have become an integral part in the work of the engineer, and make it possible to develop systems comfortable and time efficient.

The research work of a communication engineer can be divided into three main stages: in the first stage he has to become familiar with a topic, and understand the problem or challenge he needs to face. In the second stage, after deciding on the approach for the investigation, he has to realize the system under investigation on the simulation tool, and perform the needed simulations. In the third stage, simulation results have to be confirmed experimentally using a real system assembled in the lab.

This is the motivation behind this practical lab: to have the first experience from the work procedure of the engineer.

During this lab, simulations will be conducted with a self-programmed Matlab code and the chair’s simulation tool MOVE-IT (=Modular Versatile Evaluating and Interactive Simulation Tool).
