We'll need to set the phase rotation of the demodulated RF PD signals (REFL11, REFL55, AS55, POP22) to match them with what the NN expects...

Here are the demodulation phases and rotation matrices tuned for the network. For the matrices, I am assuming that the input is [I, Q] and the output is [I,Q].
POP22
phi = 153 degrees
[[-0.894, 0.447],
[-0.447, -0.894]]
REFL11
phi = 93 degrees
[[-0.058, 0.998],
[-0.998, -0.058]]
REFL55
phi = -90 degrees
[[0.000, -1.000],
[1.000, 0.000]]
AS55
phi = 7 degrees
[[0.993, 0.122],
[-0.122, 0.993]] |
