Multiple Antenna Gain in Ultra-Wideband Indoor Propagation

This paper presents an investigation on the gain that can be achieved by the application of multiple antenna techniques in ultra-wideband indoor channels. Both classic diversity approaches with only one transmitter as well as MIMO configurations with multiple antennas at transmitter and receiver are regarded. The investigations are based on deterministic indoor propagation simulations that have been conducted with a fully three-dimensional ray-optical simulator. The analysed quantity is the probability distribution of the signal to noise ratio at the receiver, which allows for the assessment of the reliability that can be obtained for data transmission.
