Abstract

In this paper we propose an improved version of a single receiver DF system that combines a PLL scheme with the MUSIC algorithm to obtain both azimuthal and zenithal angles. The new approach uses a more efficient algorithm to remove the typical ambiguities of PLL-based schemes. We carry out several experiments to assess the algorithm performance. Among them, we consider complex environments, such as wireless communication channels where the received signal is corrupted by noise and suffers from distortion, interference, and multipath effects. The new scheme is tested for BPSK and QPSK signals under these conditions. The simulated results show  superior performance of the proposed PLL algorithm when compared to previous techniques.
