Positioning Application and SimCHAN: Why is my Galileo CW power 3dB's more than the E1 CBOC open service code level power?
The E1 B and C components are modulated by orthogonal PN codes.
Therefore the total E1 code power is the sum of the individual modulated components yielding a 3 dB gain in power relative to each component.
When the modulation is off, producing a CW signal the B and C components are now in-phase.
Therefore the voltage of the composite CW signal is twice that of the voltage of the individual components.
Yields a 6 dB gain in power relative to each component.
