The minimum phase shift in 16-QAM, 64-QAM, 256-QAM etc is 0 (same value regardless of whether you are using degrees or radians!) and occurs when the symbol transition is from one constellation point on some radius vector to another constellation point on the same radius vector.

What are in phase and quadrature channels in terms of QAM scheme?
QAM is a modulation format that combines two carriers whose amplitudes are modulated independently with the same optical frequency and whose phases are 90° apart. These carriers are called in-phase carriers (I) and quadrature-phase carriers (Q). The QAM can assign states by using I and Q, which is called QAM.
What is quadrature amplitude modulation QAM and how does it work?
Key Takeaway: QAM (quadrature amplitude modulation) is a modulation scheme used by network operators when transmitting data. QAM relates to a way of changing the amplitude, or power level, of two signals. QAM enables an analog signal to efficiently transmit digital information and increases the useable bandwidth.
How many amplitudes are in QAM?
QAM (quadrature amplitude modulation) is a method of combining two amplitude modulation (AM) signals into a single channel. This approach helps double its effective bandwidth. QAM is also used with pulse AM (PAM) in digital systems, like wireless applications.
