Data Whitening


Data whitening can be considered a kind of data randomizer. Some details regarding this feature...
- This feature is available in fw version 3.44 and later.
- You can set the Data Whitening ON/OFF from the Additional setup sub-menu
-Transmitter picks up a randomized seed character (based on processor's free running clock) and inserts it in front of the user data.
-The rest of the user data in the radio frame is then "whitened" using the seed as the start key
-The receiver checks the first received character (=seed) and decodes the trailing message accordingly back to original
- This functionality must be enabled in every modem in the network, could be considered equally to the FEC on this point of view.
