Abstract :
In this paper, we derive a closed-form expression for the fading correlation function of a uniform circular array (UCA). The fading correlation for a UCA is a function of antenna spacing, array geometry, as well as the distribution of angle of arrival (AOA). Comparative results on the fading correlation function for both the uniform linear array (ULA) and the UCA are given. Computer simulations are carried out to verify the analytical results
