We are using DW1001C Module to find distance. here we want to make sure that our frames should not be decode by others and alter by others.
so when i gone through the user manual i found at 10.5 section about Dynamic preamble select.
The IEEE 802.15.4 UWB PHY standard includes a feature called dynamic preamble select (DPS) intended for use a security mechanism for two-way ranging, where devices switch to using one of the DPS specific preamble codes for the ranging exchange, and perhaps a different one for each direction of communication. The idea is to make it more difficult to eavesdrop or spoof, by randomly changing the DPS preamble codes in a mutually agreed sequence only known to the valid participants. This is supported by the DW1000 where at 64 MHz PRF the preamble codes additionally available for DPS are: 13, 14, 15, 16, 21, 22, 23 and 24.
how to implemet this in my code. what changes i need to do? can any one help me.
