Cramer Rao Lower Bound (CRLB) for Ranging with SX1280

The equation for the theoretical ranging precision limit given in the application note AN1200.29, Rev 1.0, on page 15 seems to have a mistake. According to the given Reference [5] and also the values in Fig. 11 below the equation the Bandwith BW in the denominator of the equation should be squared.

Thank you for your help,

Hello,

You are correct, there is a typo in the application note and the bandwidth term should indeed be squared.

Thanks for reporting this.
