The recent increasing requirements for high speed and robust wireless communication links have given rise to the development of THz wireless communication systems (0.3-10 THz), as a very promising alternative to their MMW and FSO counterparts. However, the performance of THz wireless systems is subject to free space path loss, signal attenuation due to humid air, atmospheric turbulence and pointing errors between transmitter and receiver terminals. Thus, in this work we first introduce the stochastic impact of generalized PEs with nonzero boresight in the THz area, while atmospheric turbulence is modeled through the suitable gamma gamma distribution. Considering also the deterministic impact of free space path loss and signal attenuation, an outage probability analysis is performed for a typical line of sight THz link. In this context, novel closed form expressions are derived. Their analytical results demonstrate the joint influence of these effects on THz signal transmissions, while simulation results validate the accuracy of our analysis.
