Abstract EN
This paper investigates the joint effects of in-phase and quadrature-phase imbalance (IQI) and imperfect successive interference cancellation (ipSIC) on the cooperative Internet of Things (IoT) nonorthogonal multiple access (NOMA) networks where the Nakagami-m fading channel is taken into account.
The closed-form expressions of outage probability for the far and near IoT devices are derived to evaluate the outage behaviors.
For deeper insights of the performance of the considered system, the approximate outage probability and diversity order in high signal-to-noise ratio (SNR) regime are obtained.
In addition, we also analyze the throughput and energy efficiency to characterize the performance of the considered system.
The simulation results demonstrate that, compared with IQI, ipSIC has a greater impact on the outage performance for the near-IoT-device of the considered system.
Furthermore, we also find that the outage probabilities of IoT devices can be minimized by selecting a specific power allocation scheme.
