Dynamic sidelobe multiplexing in beamspace MIMO systems
Karabacak, Murat; Afeef, Liza; Arslan, Hüseyin (IEEE-Institute of Electrical and Electronics Engineers Inc, 2020)Recent studies on multiplexing concept over beamspace multiple-input-multiple-output (MIMO) can reduce the need for using phase shifters while keeping the directivity performance at similar levels. Thus, beamspace MIMO ... -
Emulation techniques for small scale fading aspects by using reverberation chamber
Kihero, Abuu Bakari; Karabacak, Murat; Arslan, Hüseyin (Ieee-Inst Electrical Electronics Engineers Inc, 2019)Reverberation chambers (RVCs) are used to provide an efficient and reliable testbed for emulating the wireless channel effects in the laboratory environment. In the literature, various techniques have been studied to enrich ... -
Rf circuit implementation of a real-time frequency spread emulator
Karabacak, Murat; Mohammed, Ahmed Hossam; Özdemir, Mehmet Kemal; Arslan, Hüseyin (IEEE-Institute of Electrical and Electronics Engineers Inc, 2018)Despite their reliability, on-site measurements are time-consuming and costly actions for the evaluation of new devices. Channel emulators are widely utilized measurement instruments to generate desired environmental channel ... -
A spatially adaptive antenna array for mm-wave wireless channel control with microfluidics based reconfiguration
Mendoza, Jonas; Karabacak, Murat; Arslan, Hüseyin; Mumcu, Gökhan (IEEE-Institute of Electrical and Electronics Engineers Inc, 2020)Spatially adaptive antenna array (SAA) is an electronically scanned antenna array with capability of changing its physical location. This new capability allows SAA to control the wireless channel environment to increase ...
