comnum.theory_sdr_optimum_correction(sir_db)

The signal-to-distortion ratio (dB) of the optimum gain correction against a cochannel interferer in Rayleigh fading (Cimini 1985, eq. (21)).

Parameters:

sir_db (float | array_like) – the signal-to-interference ratio (dB).

Returns:

the SDR (dB) at every SIR.

Return type:

float | numpy.ndarray

Raises:

ValueError – for values that are not real numbers.
