Angle Diversity and Current Control," IEEE Trans.
Optical space division multiple access (SDMA) can be useful which use an angle diversity transmitter.
To solve this issue, angle diversity based optical photo detector is proposed to mitigate the LOS interference.
The TFLA is a rapidly deployable
angle diversity three meter troposcatter antenna that is a single antenna designed to support quad-diversity operation that enables the link to be setup in 30 minutes or less, a significant reduction from the traditional two antenna system.
A smart base station testbed was developed that allows direct comparison of spatial, polarization and
angle diversity. The testbed, shown in Figure 8, operates in the cellular band.
