摘要：

This work aims to present the theoretical framework for the outage performance assessment of the joint impact of antenna misalignment and local oscillator (LO) phase noise (PHN) on terahertz (THz) wireless systems. In more detail, a closed form expression for the outage probability and a tight high signal to noise ratio (SNR) approximation were extracted. Our results reveal the detrimental impact of antenna misalignment and PHN and the importance of taking them into consideration when analyzing the performance of THz wireless systems. Furthermore, it was observed that the impact of the LO hardware impairments is more significant to the system performance compared to the antenna misalignment.
