Millimeter Wave Massive MIMO Downlink Per-Group Communications with Hybrid Linear Precoding
Thomas Ketseoglou, Matthew. C. Valenti, Ender Ayanoglu
We address the problem of analyzing and classifying in groups the downlink channel environment in a millimeter-wavelength cell, accounting for path loss, multipath fading, and User…
Zero-Forcing Per-Group Precoding (ZF-PGP) for Robust Optimized Downlink Massive MIMO Performance
Thomas Ketseoglou, Ender Ayanoglu
In this paper, we propose a new, combined Zero-Forcing Per-Group Precoding (ZF-PGP) method that achieves very high gains in comparison to ZF Precoding techniques, while it simultan…
LED Selection and MAP Detection for Generalized LED Index Modulation
Manh Le Tran, Sunghwan Kim, Thomas Ketseoglou +1
In this paper, we propose light-emitting diode (LED) selection that can be applied not only to the conventional Multiple-Input Multiple-Output (MIMO) case, but also to a larger MIM…
Downlink Precoding for Massive MIMO Systems Exploiting Virtual Channel Model Sparsity
Thomas Ketseoglou, Ender Ayanoglu
In this paper, the problem of designing a forward link linear precoder for Massive Multiple-Input Multiple-Output (MIMO) systems in conjunction with Quadrature Amplitude Modulation…
