## with polarisation flipping
|
||||
|
||||
polarisation flipping: signal is randomly rotated by 180°. polarization rotation can be detected by adding a tone on one of the polarisations, but only to mod 180° with a direct detection setup. the randomly flipped signal should allow the network to hopefully learn to compensate for dispersion, pmd independently from the polarization rot. the training data includes the flipped signal as well, but no indication if the polarisation is flipped.

Parameters
|
||||
----------
|
||||
`y` is the 1-d array of signal samples.
|
||||
|
||||
`window_size` is the number of samples to show horizontally in the
|
||||
eye diagram. Typically this is twice the number of samples in a
|
||||
"symbol" (i.e. in a data bit).
|
||||
|
||||
`offset` is the number of initial samples to skip before computing
|
||||
the eye diagram. This allows the overall phase of the diagram to
|
||||
be adjusted.
|
||||
|
||||
`size` must be a tuple of two integers. It sets the size of the
|
||||
array of counts, (height, width). The default is (800, 640).
|
||||
|
||||
`fuzz`: If True, the values in `y` are reinterpolated with a
|
||||
random "fuzz factor" before plotting in the eye diagram. This
|
||||
reduces an aliasing-like effect that arises with the use of
|
||||
Bresenham's algorithm.
|
||||
|
||||
`bounds` must be a tuple of two floating point values, (ymin, ymax).
|
||||
These set the y range of the returned array. If not given, the
|
||||
bounds are `(y.min() - 0.05*A, y.max() + 0.05*A)`, where `A` is
|
||||
`y.max() - y.min()`.
|
||||
|
||||
Return Value

||||
Returns a numpy array of integers.
