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.
