MT Measure Rho
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.
Inputs/Outputs
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.
t0
Trigger (start) time of the Y array.
Default value: 0.0
dt
Time interval between data points in the Y array.
Default value: 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.
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 value: 0.0
dt
Time interval between data points in the Y array.
Default value: 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.
error in
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Default value: No error
rho
The measured rho of the received complex waveform.
error out
Error information.
The node produces this output according to standard error behavior.
Rho
| Ranges for ρ | Degree of correlation between measured and ideal signals |
|---|---|
| ρ=0.0 | Uncorrelated |
| 0.0 < ρ < 1.0 | Partially correlated |
| ρ = 1.0 | Perfectly correlated |
