Multiple input multiple output (MIMO) communication systems promise high channel capacity and data transmission rate. To obtain these characteristics, they rely on the precise knowledge of the channel state information (CSI). Several techniques are been used for channel estimation with different complexities. They vary from the conventional Least Squares (LS) method to more sophisticated ones, employing...
Recently, MIMO techniques have been using in active radars,and become a hot topic in radar field, where they improve the performance of detection and parameters estimation greatly. On estimates of direction-of-arrival (DOA) in active radars, generally elements of the receive array were closely spaced to enable direction finding measurements. However, in order to obtain angular diversity, all elements...
