Composite Rho (W-CDMA(3GPP)/HSPA)

Rho is the normalized correlation coefficient between the measured and ideal reference signals. Rho is computed by comparing the normalized correlated power between the measured signal and the reference signal and is designated as the waveform quality factor. The maximum value of Rho is 1.0 (which means the measured signal and reference signal are 100% identical).

A Rho value of 1.0 indicates that all of the transmitted power correlates with the ideal signal as determined by the detected sequence.

Rho is the correlated power for all active Code Channels (as seen in the composite CDP trace data display).

If the signal errors are uniformly distributed, then Rho approximately equals:
