sdr.PED.decision_directed_error(modem: LinearModulation, n_points: int = 1000) → tuple[NDArray[float64], NDArray[float64]]

Simulates the average phase error of the decision-directed PED using the specified modulation scheme.

Parameters:
modem: LinearModulation

The linear modulation scheme.

n_points: int = 1000

The number of points in the simulation.

Returns:

  • The true phase error in radians.

  • The detected phase error in radians.
