dc.description.abstractToday, many mobile applications rely on the location of User Equipment (UE) with a built-in wireless receiver and complementary sensors. The performance of wireless localization algorithms depends on the existence of Line-of-Sight (LOS) propagation conditions. However, the existence of Non-Line-of-Sight (NLOS) propagation conditions adds considerable errors to the measurements such as Angles of Arrival (AOA). Synthetic Array (SA) processing synthesizes an array antenna by using a single moving antenna whose short-range trajectory can be estimated precisely by some complementary sensors, which enables the use of space-time processing to deal with the NLOS problem. The main objective of this thesis is to assess the multipath degree by utilizing SA processing. An Eigenvalue Exponential Spread (EES) factor is proposed to estimate the spatial coherency and hence the multipath degree. Theoretical analysis and experiment results strongly reveal that the EES factor is capable of indicating the spatial coherency and AOA estimation performance.en_US
