The results show that the leaf state, measurement geometry and vegetation density are more important factors influencing signal attenuation than tree species or leaf shape. Generally, the 11.6 GHz ...

VVAs provide continuous adjustment of attenuation levels that can be set to any value within the given range. Analog variable attenuators are usually employed for automatic gain control circuits, ...

Figure 1b. Effects of transceiver with 9.5 db of pre-emphasis. Pre-emphasis can help overcome high frequency attenuation, but does come with some side effects due to the boosted signal: Increased ...
