During normal operation frequency response curve is smooth at the centre and central
equalizer tap is higher, while side towers evenly decrease. If equalizer taps and frequency
response curve significantly differs from the one above, it may be indication of multipath
issue, which must be inspected with use of precise and accurate path profiling. Higher taps
mainly on the right side indicate a weaker reflected signal compared to the main signal,
while higher taps mainly on the left side – stronger reflected signal.
Over The Air à Constellation diagram
A constellation diagram is a representation of a signal modulated by the digital
modulation schemes 256QAM, 128QAM, 64QAM, 32QAM, 16QAM or 4QAM. It displays the
signal as a two-dimensional scatter diagram in the complex plane at symbol sampling
instants. Measured constellation diagram can be used to recognize the type of interference
and distortion in a signal.
