Mitigation of UE Antenna Calibration Errors via Differential STBC in Cell-Free Massive MIMO

Marx M. M. Freitas, Stefano Buzzi

This letter investigates the use of differential space-time block coding (DSTBC) to address antenna array calibration impairments at multi-antenna user equipment (UE) in the downli…

Differential Space-Time Block Coding for Phase-Unsynchronized Cell-Free MIMO Downlink

Marx M. M. Freitas, Giovanni Interdonato, Stefano Buzzi

In the downlink of a cell-free massive multiple-input multiple-output (CF-mMIMO) system, spectral efficiency gains critically rely on joint coherent transmission, as all access poi…

Eliminating Phase Misalignments in Cell-Free Massive MIMO via Differential Transmission

Marx M. M. Freitas, Stefano Buzzi, Giovanni Interdonato

This paper proposes two approaches for overcoming access points' phase misalignment effects in the downlink of cell-free massive MIMO (CF-mMIMO) systems. The first approach is base…
