Hybrid OTFS/OFDM Design in Massive MIMO
Ruoxi Chong, Mohammadali Mohammadi, Hien Quoc Ngo +2
We consider a downlink (DL) massive multiple-input multiple-output (MIMO) system, where different users have different mobility profiles. To support this system, we categorize the…
Near-Field Localization with Antenna Arrays in the Presence of Direction-Dependent Mutual Coupling
Zohreh Ebadi, Amir Masoud Molaei, George C. Alexandropoulos +4
Localizing near-field sources considering practical arrays is a recent challenging topic for next generation wireless communication systems. Practical antenna array apertures with…
Near-Field Localization with an Exact Propagation Model in Presence of Mutual Coupling
Zohreh Ebadi, Amir Masoud Molaei, Muhammad Ali Babar Abbasi +3
Localizing near-field sources considering practical arrays is important in wireless communications. Array-based apertures exhibit mutual coupling between the array elements, which…
How to Combine OTFS and OFDM Modulations in Massive MIMO?
Ruoxi Chong, Mohammadali Mohammadi, Hien Quoc Ngo +2
In this paper, we consider a downlink (DL) massive multiple-input multiple-output (MIMO) system, where different users have different mobility profiles. To support this system, we…
