What is Noise and Interference about?

The performance of a communication system does depend not only on the strength of the signal at the receiver but on its relative strength when compared to any other non-desired signal, such as noise and interference. Given the limited power of THz transceivers and the high propagation losses of the THz channel, understanding and either minimizing or leveraging the noise and interference at the receiver are of key importance. In this chapter, the main noise and interference sources at THz frequencies are described, with a special emphasis on the molecular absorption noise and the multi-user interference in different application scenarios at the nano-and macro-scales. Molecular Absorption Noise Beyond the conventional noise sources intrinsic to the transceiver device technology, such as the thermal noise associated with electronic receivers or the photon-counting or shot noise associated with photonic receivers, the THz channel introduces a new type of noise, namely, the molecular absorption noise. Reciprocal to the process by which the absorption of THz radiation leads to internal vibrations in different types of molecules (e.g., water vapor), vibrating molecules result in the emiss
