In this study, interference modelling is investigated for fixed terrestrial microwave LOS (line-of-sight)/ NLOS (transhorizon) radio links operating in NATO Band 3+ (1350-2690 MHz) and NATO Band 4 (4400-5000 MHz) frequency bands. The calculation of the interference due to both clear-air and hydrometeor scattering interference mechanisms are made for the interfered-with receiver stations of fixed terrestrial point-to-point systems. Moreover, interference propagation mechnasims of the calculation of the clear-air interference basic transmission loss mentioned in the Rec. ITU-R P. 452 are examined. Interference analysis for several microwave radio links are analyzed using the interference propagation parameters such as interfering transmitter and interfered-with receiver station coordinates, antenna heights above ground level, antenna discrimination, polarization, radio refractivity index lapse, sea-level surface refractivity, time percentage for which the calculated basic transmission loss is not exceeded, clutter information, digital terrain elevation and climate data. © 2015 IEEE.

Evaluating spatial diversity technique for mitigating multipath fading of fixed terrestrial point-to-point systems Goktas P.; Topcu, S.; Karasan, E.; Altintas, A. (Institute of Electrical and Electronics Engineers Inc., 2015)Multipath fading is the dominant propagation factor for fixed terrestrial microwave line-of-sight (LOS) radio links operating at frequencies below 10 GHz. Fading due to multipath propagation attenuates received signals on ...
Arslan, H.; Yarkan S.; Sahin, M. E.; Gezici, S. (Cambridge University Press, 2011)Wireless systems are commonly affected by interference from various sources. For example, a number of users that operate in the same wireless network can result in multiple-access interference (MAI). In addition, for ...
