What will happen to the constellation if the amplitude and series of two orthogonal signals are changed?

In this case, the constellation diagram has the following two changes:

1. amplitude variation: the amplitude of orthogonal signals determines the intensity or energy of each point in the constellation. Increasing the amplitude will make the points in the constellation more concentrated and prominent, indicating that the signal strength is higher. Decreasing the amplitude will cause the points in the constellation to become blurred or scattered, which indicates that the signal strength is reduced.

2. Series change: The series of orthogonal signals determines the number of discrete points that may exist in the constellation. Increasing the number of series can show more discrete points, indicating that signals can convey more information. Reducing the number of series will reduce the number of discrete points in the constellation, indicating that the signal can transmit less information.
