Abstract
As one key technology in third generation communication, smart antenna can effectively increase system capacity and reduce co-channel interference for deployment and implementation of information and communication technologies in the Smart Cities. This article expounds in detail how to obtain Direction of Arrival (DOA) information using Multiple Signal Classification (MUSIC) algorithm with Uniform Circular Arrays (UCA) based on theoretical analysis of receiving spatial signal by uniform circular arrays. A number of simulation results were carried using MATLAB and compared with the experimented one. The comparison show that proposed MUSIC algorithm is more accurate and stable.
