  In this paper we propose an approach that uses homodyne receivers to design
smart antenna systems. The receivers functions are to detect angles of arrivals
of seven incoming RF signals using MUSIC or ESPRIT algorithms. The
characteristics of each algorithm are critical for the systems precision as
well as receivers types. Results are deduced from the simulation of each
system, using the Advanced Design System (ADS) and MATLAB. These are compared
to results deduced from real systems in the WIMAX (3.5GHz) domains.
