Calculates rho given an acquired and ideal waveform.

Rho is a measure of correlation between the measured complex waveform and the ideal complex waveform. To generate the ideal waveform, use the digital modulation nodes with the same system parameters given to the digital demodulation nodes, and then modulate the output bit stream returned by the demodulation node.

received complex waveform

The actual output waveform from the digital demodulation node. Wire the recovered complex waveform parameter from the digital demodulation node to this parameter.

datatype_icon

t0

Trigger (start) time of the Y array.

Default: 0.0

datatype_icon

dt

Time interval between data points in the Y array.

Default: 1.0

datatype_icon

Y

The complex-valued signal-only baseband modulated waveform. The real and imaginary parts of this complex data array correspond to the in-phase (I) and quadrature-phase (Q) data, respectively.

datatype_icon

ideal complex waveform

The reference waveform. Obtain this waveform by remodulating the output bit stream from the digital demodulation node.

t0

Trigger (start) time of the Y array.

Default: 0.0

dt

Time interval between data points in the Y array.

Default: 1.0

Y

The complex-valued signal-only baseband modulated waveform. The real and imaginary parts of this complex data array correspond to the in-phase (I) and quadrature-phase (Q) data, respectively.

datatype_icon

error in

Error conditions that occur before this node runs. The node responds to this input according to standard error behavior.

Default: no error

datatype_icon

rho

The measured rho of the received complex waveform.

datatype_icon

error out

Error information. The node produces this output according to standard error behavior.
