Abstract

In this paper we compare the performance of conventional subspace-based direction-of-arrival (DOA) estimation techniques such as ESPRIT and MUSIC with the integrated approaches that combine the constant modulus algorithm with subspace-based techniques. Simulated and measured results are presented for a variety of signal conditions. The integrated approach was found to perform significantly better than the conventional ESPRIT approach. Also, multipath present in the channel significantly degrades the performance of the DOA estimation algorithms, and this has been confirmed by measurement and ray tracing simulation. This work has application to smart antennas and position location.
