need more clarification on carrier integrator

hi all,

[color=#333333]i went through DWM1000_user_manual ver2.12 and found the following paragraph “The DW1000 receiver needs to compensate for frequency offsets between the timing references at the transmitting device and itself to successfully receive a packet. Therefore, when a packet is successfully received, the DW1000 has a sufficiently accurate estimate of the frequency offset.” [/color]

[color=#333333]if receiver has already compensated for frequency offsets and is giving the offset value through carrier integrator how is it useful to us in increasing the accuracy of ranging?[/color]

[color=#333333]my main concern is if carrier integrator value can be used for synchronizing two decawave modules?[/color]

[color=#333333]please reply![/color]

The Carrier integrated was introduced earlier this year (API 2.4) to improve TOF calculation results of SS-TWR where the remote responder unit’s clock is a number of PPM offset from the local initiator unit’s clock.
And so how it can help you depends on your Two-Way Ranging method.
