	where  indicates the amount of power on the high frequency BOC(6,1) component:		where <math>\rho</math> indicates the amount of power on the high frequency BOC(6,1) component:

	As we can recognize in the figure above, the shape of the auto-correlation function highly depends on the amount of power on BOC(6,1). Indeed, the higher the value of , the more ripples the auto-correlation will present and the better the potential performance will be. Furthermore, it is interesting to see that the sharpest slope around the origin is shown by TMBOC and the version while TMBOC(6,1,2/11) and perform similar. MBOC is analyzed next regarding the following three criteria:		As we can recognize in the figure above, the shape of the auto-correlation function highly depends on the amount of power on BOC(6,1).

== CBOC Implementation ==

The CBOC implementation is a particular case of the [[CBCS Modulation]]. The CBOC modulation can be expressed as follows

::[[File:CBOC_Eq_1.png|none|500px]]
::[[File:CBOC_Eq_2.png|none|500px]]

where we can recognize that in this particular case the [[Binary Coded Symbols (BCS)|BCS]] component is [[Binary Offset Carrier (BOC)|BOC(6,1)]] with a percentage of power of 1/11. Furthermore the high frequency signal is placed on both the data and pilot channels and equal power for both channels is assumed. In addition, the total Galileo Open Service (OS) power is equal to that of the PRS and the modulation parameters are the following:
