Index modulation (IM) has emerged as a promising technique for improving spectral efficiency and hardware efficiency in next-generation communication ...

Not all sportsbook promos are created equal. Some reward you just for signing up. Others require a winning bet, a losing bet, or a very specific set of circumstances. We cut through the fine print so ...

Abstract: In recent years, densifying multiple-input multiple-output (MIMO) has attracted much attention from the communication community. Thanks to the subwavelength antenna spacing, the strong ...

Abstract: Due to the large number of antennas in the antenna array, channel estimation for millimeter-wave (mm-Wave) massive MIMO becomes complex. Leveraging the sparsity of mm-Wave channels is an ...
