comnum.monte_carlo_mi(rx, tx, constellation, *, px=None)#

Symbol-wise mutual information for a Gaussian channel of the measured noise variance (OptiCommPy monteCarloMI; the transmitted symbols are snapped to the constellation, so that the estimate never exceeds H(X)).

Parameters:

  • rx (array_like) – the received symbols.

  • tx (array_like) – the transmitted symbols.

  • constellation (Constellation) – the alphabet.

  • px (array_like, optional) – prior probabilities of the points (uniform by default).

Returns:

the mutual information (bits/symbol).

Return type:

float

Raises:

ValueError – for an invalid parameter or input (the message names it).
