Abstract:

In this paper, based on parametric channel modeling, we present a direction of arrival (DoA) estimation method for multi-cell multi-user 3D massive-MIMO/Full Dimension multiple-input multiple-output (FD-MIMO) orthogonal frequency division multiplexing (OFDM) system. Using estimation of signal parameter via rotational invariance technique (ESPRIT), we investigate into the performance of DoA estimation for two possible scenarios- first, for the case where no angular domain overlapping from interference signals exists with the target user's DoAs, and second, for the case where a number of DoAs of the target user's channel are completely overlapped with DoAs from interference signals, to be specific, from pilot contamination.
