This paper investigates the Bluetooth direction finding technique and combines it with the
improved signal subtraction subspace (ISSS) algorithm for precise indoor positioning. First …

Antenna arrays are used for signal processing in sonar and radar direction of arrival (DOA)
estimation. The well-known array geometries used in DOA estimation are uniform linear …

Indoor positioning remains as one of the major challenges of the Internet of Things (IoT),
where assets are usually deployed over environments where the Global Navigation Satellite …

Several works show that the linear Angle of Arrival (AoA) methods such as Projection Matrix
(PM) have low computational complexity compared to the subspace methods. Although the …

With the rapid development of the Internet of Things (IoT) technology, location-based
services (LBSs) are gaining significant attention for their potential applications. Among the …

This manuscript firstly proposes a reduced size, low-complexity Angle of Arrival (AoA)
approach, called Reduced Uniform Projection Matrix (RUPM). The RUPM method applies a …

The way and size of matrix sampling have significant effects on the obtained eigen/singular
values and the corresponding eigen/singular vectors of the sample matrix. Thus, this work …

A Non-Uniform Sampling (NUS) methodology is presented, which improves the Angle of
Arrival (AoA) estimation accuracy. The proposed sampling methodology is applied to extract …

This thesis is concentrated on the Angle/Direction of Arrival (A/DOA) estimation and
Beamforming techniques that can be used in the current and future engineering applications …

As the antenna array is the first stage used in the direction-finding systems, then any error in
the position of such sensor array will affect the whole system performance. To this end, this …
