Analysis of various Interference in Millimeter-Wave Communication Systems: A Survey

Millimeter wave (mmWave) communication is considered as key enabler for Fifth-generation (5G) mobile system. The mmWave has radio spectrum ranging from 30 to 300 GHz, known as Extremely High Frequency (EHF). It provides super-speed connectivity, larger data rated, high spectral efficiency and more reliability. Due to increased sensitivity of signals in mmWave frequency, it may produce large Interference and Path-loss. These interferences arise due to buildings blockage, IQI, IQTM, Inter-Carrier Interference, Inter-Block Interference, PAPR, Rain Scatters, Phase Noise, Shadowing, Reflections, Phase Locked Oscillators, Local Oscillators, Propagation loss, Attenuation, hardware issues and Computational complexity. Because of the obstructions, the Signal-to-noise ratio will be decreased due to increase in the interference power. For avoiding these distortions, various Interference Compensation and Estimation techniques are used. This paper summarizes interference occurred in 5G systems (i.e) Millimeter wave systems and also gives the extensive review of various interference models.
