How do you normalize IQ data?

Normalize IQ Traces enables or disables IQ trace normalization. Selecting the Normalize IQ Traces check box enables normalization; clearing the check box disables normalization. When normalization is ON, the VSA normalizes, or scales, the demodulated trace data results.

Can we say that 256-QAM is better than 16-QAM in terms of bandwidth efficiency?

As the level increases, QAM technique becomes more bandwidth efficient but it requires very robust algorithms in order to decode complex symbols to bits at receiver. For example 256-QAM is complex than 16-QAM. QAM is more bandwidth efficient compare to BPSK but it is less robust.

How do you make a QAM signal?

The basic way in which a QAM signal can be generated is to generate two signals that are 90° out of phase with each other and then sum them.

What is highest QAM modulation?

“The 802.11be standard increases the QAM modulation order to 4096 QAM to achieve the highest data rate.
