Abstract: The thesis presents the peer-to-peer wireless channel characterization study for two urban environment settings in military UHF band based upon measurement campaigns conducted in two distinctive places in Singapore which feature urban high rise indoor-to-indoor and outdoor-to-indoor channel propagation. The Military UHF frequencies were the selected frequencies ranging from 250 to 470 MHz. To date, few publications have been done to characterize the propagation features of low-rise and high-rise urban channels in the frequency band. There have been even fewer could be found on the characterization of the wireless channels in terms of distribution modeling of the multipath components and delay dispersions. Our measurements employed a separate transmitter and a receiver, from which both path loss and delay dispersion characteristics were analyzed for link distances of up to 2.8 km from the measurements of two kinds: one by fixing both transmitter and receiver in the indoor environment, the alternative by fixing only the receiver in the indoor environment and moving the transmitter along the designated routes. As a result, log-distance path loss models and link availability are described; power delay profile decay rate and delay dispersion characteristics are presented. 3-D ray tracing simulations are performed to explain propagation mechanisms. These results serve as useful immediate references for implementation of reliable and robust wireless communication systems in similar environments under warfare condition.
