Abstract: Large antenna arrays are used at both the transmitter and the receiver for massive multiple-input multiple-output (MIMO) systems, which poses a challenging issue in channel estimation.
After U.S. strikes and the capture of Nicolás Maduro, President Donald Trump said Washington was “going to run the country” ...
Abstract: In massive multiple-input multiple-output (MIMO) systems, attaining precise channel state information (CSI) tends to cause significant pilot overhead and prohibitive computational complexity ...
