“…In [6], the effect caused by nonlinear amplifiers is quantified as the degradation of the EVM, and the reception performance of the downlink NOMA for two user equipment (UE) is evaluated. Figure 1 shows the system model of the downlink power-domain NOMA when there are two UEs.…”

“…However, the power domain NOMA systems face a major limitation due to the adverse impact of nonlinear distortions in the radio frequency (RF) circuits on the multiplexed signals [6], [7]. The signal for a user near the base station (BS) is assigned a small power as it differentiates the transmitting power for users based on their propagation loss and required SNR.…”

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD). Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD. The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC). Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.
