preamble
Two possible burst structures are supported. First one is used in the case of unencrypted burst, and second one is
devoted to encrypted bursts.
5.3.1 Unencrypted Burst Structure
When Cripto AES bit in the Burst Header is set to 0, the burst shall be composed by a Burst Header delimiter
followed by a data payload including one or several fragmented and/or completed packets. A Burst Header delimiter
without any following data payload is used to send PAP information when there are no data to be sent as described
in section 5.2.2.
Note: The Burst Header is a delimiter processed by the PHY layer as described in 3.3.1. It is transmitted in HURTO
mode over one single symbol. The data payload is processed by the PHY layer as described in 3.3.2. The data
payload may use HURTO or adaptive mapping. It can be transmitted over one or several symbols.
The Unencrypted Burst could have the following structures:
