Ergodic Capacity Analysis of AF DH MIMO Relay Systems with Residual Transceiver Hardware Impairments : Conventional and Large System Limits
Papazafeiropoulos, Anastasios K.; Sharma, Shree Krishna; Chatzinotas, Symeon; Ottersten, Bjorn (2017-08-31)Despite the inevitable presence of transceiver impairments, most prior work on multiple-input multiple-output (MIMO) wireless systems assumes perfect transceiver hardware, which is unrealistic in practice. In this direction, ... -
Impact of Phase-Noise and Spatial Correlation on Double-RIS-Assisted Multiuser MISO Networks
Abdullah, Zaid; Papazafeiropoulos, Anastasios; Kisseleff, Steven; Chatzinotas, Symeon; Ottersten, Bjorn (2022-05-17)We study the performance of a phase-noise impaired double reconfigurable intelligent surface (RIS)-aided multiuser (MU) multiple-input single-output (MISO) system under spatial correlation at both RISs and base-station ...
