The need to improve the capacity of wireless networks, for the data transmission and multimedia applications of the digital communication systems, has to focus on MIMO communication techniques to increase the data rate and the quality of services. MIMO systems use antenna arrays at both the transmit and the receive sides of a radio link and exploit the spatial dimension for the transmission. The performance of a communication system can be evaluated using a hardware simulator of radio propagation channels. This Ph.D. deals with the design and the implementation of the digital block of a hardware simulator of MIMO propagation channels, for both UMTS and WLAN networks. The hardware simulation of radio channel provides the necessary processing...
