Lattice-Based mmWave Hybrid Beamforming [PDF]

IEEE Transactions on Communications, 2021
Conventional hybrid precoding and combining based transceivers require a large number of high-resolution radio frequency (RF) phase shifters (PSs), which impose prohibitive hardware costs and power consumption. To address the above issue, both partially connected RF PSs and low-resolution PSs have been proposed. However, the performance limits of these

Impact of reflections in enclosed mmWave wearable networks [PDF]

, 2015
We study the impact of signal reflections in enclosed/nwireless networks of wearable devices operating at mmWave/nfrequencies. Given the radical blockage by obstacles and people/n(including the user’s own body) at these frequencies, surface/nreflections ...

Shadowed FSO/mmWave Systems With Interference [PDF]

IEEE Transactions on Communications, 2019
We investigate the performance of mixed free space optical (FSO)/millimeter-wave (mmWave) relay networks with interference at the destination. The FSO/mmWave channels are assumed to follow Malaga-M/Generalized-K fading models with pointing errors in the FSO link.
