Abstract
The objective of this thesis is to design, build and evaluate a direction-of-arrival

measurement system using an antenna array operating at 2050 MHz. The first phase of the

project is an extensive study of various high resolution DOA estimation algorithms. The

algorithms studied include subspace-based techniques such as the MUSIC (MUltiple

Signal Classification) and ESPRIT (Estimation of Signal Parameters via Rotational

Invariance) algorithm, and the integrated approaches which combine property restoral-based

techniques such as the Iterative Least Squares Projection-based Constant Modulus

Algorithm (lLSP-CMA) with subspace-based techniques. All these algorithms were

simulated in MATLAB and their performance under different conditions were tested and

compared. In the second phase of the project a six element uniformly spaced linear array

receiver was built. Three Ariel DSP-96 boards based on the Motorola DSP96002 are used

to simultaneously sample, collect, and store data from each of the array elements. The data

collected by the DSP boards are processed off-line to estimate the directions of arrival.

Several experiments are conducted to test the functioning of the system under various

conditions, and demonstrate the performance of different algorithms. Results of these

experiments are also presented in this thesis.
