Kalman Filter Based MIMO CSI Phase Recovery for COTS Wifi Devices

Chu Li, Jeremy Brauer, Aydin Sezgin, Christian T. Zenger

ICASSP 2021accepted

Recently channel state information (CSI) measurements from commercial multi-input multi-output (MIMO) WiFi systems have been ubiquitously used for different wireless sensing applications. However, the phase of the CSI realizations is usually distorted severely by phase errors due to the hardware imp…

Hybrid Beamforming: Where Should the Analog Power Amplifiers Be Placed?

Yasemin Karacora, Ali Kariminezhad, Aydin Sezgin

ICASSP 2019accepted

In this paper we study the spectral efficiency (SE) of a point-to-point massive multiple-input multiple-output system (P2P-massive MIMO) with limited radio frequency (RF) chains, i.e., analog-to-digital/digital-to-analog (D2A/A2D) modules, at the transceivers. The resulting architecture is known as…
