Abstract

This paper presents technique of two dimensional direction of arrival (DOA) estimation of a source using uniform circular array (UCA) and channel state information (CSI). In orthogonal frequency division multiplexing (OFDM) system signal is simultaneously transmitted over subcarriers with different frequencies. CSI is a value that describes complex gain/attenuation and phase shift introduced by wireless channel/environment on every subcarrier. Noting the fact that CSI values among antennas and subcarriers include phase shift due to DOA and Time-of-Flight (ToF), a novel technique of virtually extending the number of antennas by estimating the DOA and ToF at the same time is described. Simulation results show that accurate DOA estimation can be achieved even with small number of antennas.
