Best Beam Index Visualization
Example
Best Beam Index (Single Beam)
Best Beam Index (All Beams)
Note
Best Beam Index (Single Beam)
displays where the selected index best peak
is found over all locations.
Best Beam Index (All Beams)
gray codes the indices for
the different selected indices. In an ideal scenario, the beam you selected should be
the best for the direction that it was intentionally created for, however, in certain
cases the index that best suits the direction is not the expected index. The
visualization makes it easier to quickly detect a problem with your codebook.
File Format for Measurement Results
You must save your measurement results as a CSV file to load them into the mmWave OTA
Test Visualizer.
