Mask-Compliant Clipping-Aware Precoding for Multi-User MIMO-OFDM Systems

Navid Reyhanian, Parisa Ramezani, Emil Björnson

Orthogonal frequency-division multiplexing (OFDM) is widely adopted in frequency-selective channels for its ability to simplify equalization, yet it also causes large signal peaks,…

Symbol-Level Mask-Compliant Hybrid Precoding for Multi-User MIMO-OFDM Systems

Navid Reyhanian, Parisa Ramezani, Emil Björnson

Millimeter-wave (mmWave) technology is a crucial enabler for next-generation networks because it offers substantially greater available bandwidth. mmWave multiple-input multiple-ou…

Joint and Streamwise Distributed MIMO Satellite Communications with Multi-Antenna Ground Users

Parisa Ramezani, Emil Björnson

We consider a low Earth orbit downlink communication, where multiple satellites jointly serve multi-antenna ground users, transmitting multiple spatial streams per user. Using a li…
