Impact of Frequency Selective Channels on a Line-of-Sight MIMO Microwave Radio Link
2010 IEEE 71st Vehicular Technology Conference, 2010Two line-of-sight (LoS) multiple-input multiple-output (MIMO) systems for point-to-point microwave radio links are simulated and analyzed. Both 2x2 spatially-separated, single-polarized and 4x4 spatially-separated, dual-polarized systems are considered in the presence of a frequency selective and time varying channel.

Further results of angle and space diversity measurements on a line-of-sight radio link
IEEE Global Telecommunications Conference, 1989, and Exhibition. 'Communications Technology for the 1990s and Beyond, 2003An experiment conducted to compare angle and space diversity improvement factors over a 51-km path in the east of England has been in progress since early 1988. Angle diversity has been implemented by using two separate parabolic antennas with angular separation between their bore-sights.

Effect of Interference Source with Directional Antenna on Radio Link in Non-Line-of-Sight Conditions
2018 Progress in Electromagnetics Research Symposium (PIERS-Toyama), 2018Fifth generation (5G) systems will be based on the frequency bands used by current cellular systems and WiFi networks, but also at higher frequency ranges. However, a signal attenuation increases as the frequency increases. Hence, directional antennas and beamforming will be used in the 5G systems.

Low cost dual reflector antennas for short-haul line of sight microwave radio links
Proceedings of the 2001 SBMO/IEEE MTT-S International Microwave and Optoelectronics Conference. (Cat. No.01TH8568), 2002In this paper a set of four low cost electrically small dual reflector antennas for radio-relay application are presented. The antennas use the same main and subreflector profiles integrated to distinct feed chains designed for each of the four proposed frequency bands. Significant theoretical analysis and preliminary experimental results in the 22 GHz

AbstractThis paper proposes a prediction method for cross‐polarization discrimination (XPD) during multipath fading on line‐of‐sight propagation paths that encounter strong surface‐reflected waves. This prediction method is required for the design of radio‐relay systems.First, the so‐called C parameter has been used widely to predict XPD but without ...
