Measures the number of bit or symbol errors at the given signal-to-noise ratio (SNR).

Parameters:¶

snr: float¶

The signal-to-noise ratio (SNR) in dB. This can be \(E_b/N_0\), \(E_s/N_0\), \(S/N\), \(C/N_0\), or other SNR quantities. However, users are cautioned to be consistent for a given class instance.

x: ArrayLike¶

The transmitted bits or symbols \(x[k]\).

x_hat: ArrayLike¶

The received bits or symbols \(\hat{x}[k]\).

Returns:¶

• The number of errors.

• The number of bits or symbols.

• The error rate.
