Modelling and simulation of indoor radio channels

Starting from the physical propagation mechanisms in indoor environments, a channel model for wideband, indoor propagation channels is developed. The model is flexible enough to accommodate various parameters such as system bandwidth, spatial distribution of scatterers, and maximum delay of propagation paths. A software simulation tool allows the generation of samples of the time-invariant complex channel impulse response. These can be used to evaluate and optimize the system performance by software simulation. In addition to the software simulator, a hardware channel simulator is built. It provides the possibility for real-time tests of radio receivers under realistic, yet well defined, channel conditions.<
