Estimation¶

Signal-to-noise ratio¶

sdr.composite_snr(snr1: ArrayLike, snr2) → NDArray[float64]

Calculates the signal-to-noise ratio (SNR) of the product of two signals.

Time domain¶

sdr.toa_crlb(snr: ArrayLike, time, ...) → NDArray[float64]

Calculates the Cramér-Rao lower bound (CRLB) on time of arrival (TOA) estimation.

sdr.tdoa_crlb(snr1: ArrayLike, snr2, ...) → NDArray[float64]

Calculates the Cramér-Rao lower bound (CRLB) on time difference of arrival (TDOA) estimation.

Frequency domain¶

sdr.foa_crlb(snr: ArrayLike, time, ...) → NDArray[float64]

Calculates the Cramér-Rao lower bound (CRLB) on frequency of arrival (FOA) estimation.

sdr.fdoa_crlb(snr1: ArrayLike, snr2, ...) → NDArray[float64]

Calculates the Cramér-Rao lower bound (CRLB) on frequency difference of arrival (FDOA) estimation.
