Abstract EN
The effects of hardware impairments with imperfect channel estimation for cache-enabled UAV networks are studied in this paper.
The effects of the setup parameters, such as the number of cached or relaying nodes, the hardware impairment factor, the channel estimation error, and the transmission SNR, on the outage probability are present by deriving the exact closed-form expressions on outage probability.
Also, the asymptotic results are present when the transmission SNR is large enough.
From the asymptotic analysis, we can see that there is an error floor introduced by the hardware impairments and imperfect channel estimation.
Specifically, the error floor is dependent on the channel estimation error factor, the hardware impairment distortion factor, and the QoS requirements.
And the diversity order of the error floor for the cached/relaying links is equal to the number of cached/relaying UAV nodes.
