Mobile Channel Simulation Models

Background

In research and development of wireless communication systems a special role is assigned to an adequate mathematical representation of physical propagation channels. It can be justified by the fact that in wireless communication systems, a typical schematic representation of which is shown in the diagram below, the limit on the transmitted data rate almost solely depends on the properties of the propagation medium. Therefore, for the design and performance evaluation of any wireless communication system, a reliable mathematical model is required, which accurately reflects the most important characteristics of the real-world wireless channels.

Planned Research

The main purpose of this work is to develop a method, which allows creating wireless channel simulation models based on the measurement data. The method should be applicable to a broad variety of the operational environments.

It is required that the statistical properties of the resulting channel simulation model closely approximate similar statistical properties of the real-world channel, estimated from the measurement data.

A special interest represents the case of multiple-input multiple-output (MIMO) systems. In these systems both the transmitter and the receiver are equipped with multiple antennas. The channel simulation models for the MIMO communication systems should reflect the statistical characteristics of the measured channel not only with respect to time and frequency, but also with respect to space.

Ph.D. Student: The Ph.D. student working on this topic at UiA is Mr. Dmitry Umansky.
