Abstract

The paper reports on the performances of training-based channel estimation methods in a multiple input multiple output (MIMO) communication system with transmitter equipped with a uniform linear array (ULA) and receiver equipped with either uniform circular array (UCA) or uniform linear array (ULA). In the undertaken investigations, the receiver is assumed to be free from any obstacles while the transmitter is surrounded by scattering objects. Spatial correlation for the ULA and UCA receiving antenna cases is determined under the Laplacian distribution of angle of arrival (AOA).
