Modulation Parameters, used in the Transmitter PDU

This section specifies the Modulation Parameters in the Transmitter PDU.

CCTT SINCGARS Modulation Parameters

Detailed information about the CCTT SINCGARS (Radio System Type 6) shall be communicated by using the Modulation Parameters in the Transmitter PDU. The Modulation Parameters shall contain the following fields:

1. FH Data - These fields are only used when the SINCGARS radio is in FH mode. They determine the hopping pattern of the SINCGARS radio. If any one of these fields is different, except FH Synchronization Time Offset, the hopping pattern is different. Radios on different hopping patterns shall not communicate.

a) FH Net ID - This field shall identify the frequency hopping network.

b) Hop Set ID - This field shall identify the set of frequencies used when creating a hopping pattern. The frequencies in the hop set are transmitted by a method outside the scope of this standard.

c) Lockout Set ID - This field shall identify the set of frequencies that are excluded from the hopping pattern. The frequencies in the lockout set are transmitted by a method outside the scope of this standard.

d) Transmission Security Key - This field shall identify the transmission security key that is used when generating the hopping pattern. (Not currently implemented, field added for future use).

e) FH Synchronization Time Offset - This field shall identify the offset to exercise time in seconds for the clock in the SINCGARS radio. SINCGARS radio clock must be synchronized for the radios to communicate. (Not currently implemented, field added for future use).

2. Start of Message - This field shall specify whether the radio is starting or continuing a transmission. A SINCGARS radio shall not receive any part of an FH transmission if the Start of Message is missed. Start of message may be missed if the radio was transmitting, receiving a different radio or otherwise not ready to start receiving a transmission.

3. Clear Channel - This field shall specify that the transmission is not subject to propagation loss, interference, comsec or any other form of signal degradation. Clear channels are used for interoperability with older systems and for control purposes.

Transmitting Terminal Primary Mode - Defines the primary mode of operation of the transmitting terminal. See section 9.1.7.2.1 for details

Transmitting Terminal Secondary Mode - Defines the secondary mode of operation of the transmitting terminal. See section 9.1.7.2.2 for details

Synchronization State - Defines the current synchronization state of the transmitting terminal

Network Synchronization ID - For TSA modes 0-2, it shall be set to default. For TSA modes 3-4, it shall be a 32-bit random integer generated by using the DIS timestamp as the seed. Only an NTR can generate a Network Synchronization ID; all other participants shall use the ID obtained from the NTR to which they are synchronized
