PAPR-Limited Precoding in Massive MIMO Systems with Reflect- and Transmit-Array Antennas
Ali Bereyhi, Vahid Jamali, Ralf R. Müller +3
Conventional hybrid analog-digital architectures for millimeter-wave massive multiple-input multiple-output (MIMO) systems suffer from poor scalability and high implementational co…
Chemical Reactions-based Detection Mechanism for Molecular Communications
Trang Ngoc Cao, Vahid Jamali, Wayan Wicke +4
In molecular communications, the direct detection of signaling molecules may be challenging due to a lack of suitable sensors and interference in the environment. Motivated by rese…
Resource Allocation for Multi-User Downlink MISO OFDMA-URLLC Systems
