Future radio communication systems with more than one antenna (Multiple Input Multiple Output, MIMO) promise to improve the data rate dramatically. This potential improvement depends strongly on the properties of the radio channel, which need to be modeled appropriately for simulation purposes. In this thesis, a new multi-antenna radio channel model will be developed.
Commonly proposed MIMO techniques will be introduced and their performance will be simulated in conventional channel models and in the newly developed one. The possible performance improvement due to MIMO and its limitations will be explained using the new radio channel model.
