Comment:
Characterized by two indices: (S4) is the coefficient of variation of intensity [standard deviation divided by mean] and (Sigma Phi) is the standard deviation of the phase of the radio signal. Typically observed in GPS signals operating at 1.58 and 1.23 GHz and relevant for all transionospheric transmissions.
