Demodulates the pulse-shaped complex samples into decimal symbol decisions.

This method applies matched filtering and maximum-likelihood estimation.

Parameters:¶

x_tilde: ArrayLike¶

The received pulse-shaped complex samples $\tilde{x}[n]$ to demodulate, with sps samples per symbol and length sps * s_hat.size + pulse_shape.size - 1.

Returns:¶

• The decimal symbol decisions $\hat{s}[k]$, $0$ to $M-1$.
