On the Achievable Rate of Hardware-Impaired Transceiver Systems [PDF]
GLOBECOM 2017 - 2017 IEEE Global Communications Conference, 2017 In this paper, we accurately model the transceiver hardware impairments (HWIs) of multiple-input multiple-output (MIMO) systems considering different HWI stages at transmitter and receiver. The proposed novel statistical model shows that transceiver HWIs transform the transmitted symmetric signal to asymmetric one. Moreover, it shows that the aggregate

Cooperative relaying in underlay cognitive systems with hardware impairments [PDF]
AEU - International Journal of Electronics and Communications, 2015 The performance of an underlay cognitive (secondary) dual-hop relaying system with multiple antennas and hardware impairments at each transceiver is investigated. In particular, the outage probability of the end-to-end (e2e) communication is derived in closed-form, when either transmit antenna selection with maximum ratio combining (TAS/MRC), or TAS ...
