Abstract

The degree of response of a receiving adaptive antenna array to signals arriving at its terminals can be varied by changing the number of elements and processing of the outputs of the individual elements. The combination of the elements and signal processing act as filter in space. In this paper, the authors present the results of simulation as they investigate the impact on signal Direction of Arrival (DOA) estimation of the number of elements. The technique used is the subspace-based and eigen-analysis method of Multiple Signal Classification which is an efficient algorithm for real time optimization of signal/interference relation in mobile wireless communication.
