Analytical MIMO Channel Representations for System Design
To enable the explicit design of MIMO techniques, mathematical representations are required. While physical models reproduce the properties of MIMO channels by specifying the locations of obstacles and the array configuration in various scenarios (see Chapter 4), so-called analytical models provide a mathematical representation of the channel matrix. A major difference between both types of modeling approaches lies in the fact that analytical models only provide a framework, but do not give fully quantitative information, unless they are parametrized by means of extrinsic information. By contrast, models such as the WINNER model or a ray-tracing tool directly yield values of ...
