Zusammenfassung:In this paper, we study the accuracy of smart antenna systems that use homodyne receivers to estimatethe angles of arrivals of incoming RF signals.The stability of the receiver in a smart antenna system plays an important role in thedetection capability. Two main types of receivers are used in this study: the six port and the five port reflectometers. We present our study by implementing MUSIC algorithm at the output of two different homodyne receivers. The results are deduced from the simulation of the characteristics of each system, using the Advanced Design System (ADS) and MATLAB.
