STANAG 4539
STANAG 4539 standard provides a family of coded data rates from 75 to
9600 bps and an uncoded data rate of 12k8 bps. In addition, these
waveforms incorporate AUTOBAUD. STANAG 4539 is an attractive choice for
Automatic-Repeat-Request (ARQ) systems.
For this waveform the RM6 modem
supports the DTE modes Standard Async, High-speed and synchronous.
Table 1 presents the complete STANAG
4539 suite of waveforms. Included in the table are the modulation, code
rate and interleaver settings for each data rate. The lower rates
include Tone Excision (TEX) (see TEX column table below). Cancellation
of up to 4 tones is possible.

The following tables give performance results for the
RM6 unit for various data rates. The results
were established using an HF Channel Simulator.
An AWGN channel is representative of ground wave propagation while the
POOR channel represents skywave conditions. A RICEAN channel has a
steady (specular) component and a fading component, thus representing a
mixture of the ground and skywave propagation scenarios

uncoded data rate of 4800 bps is supported.
For this waveform the RM6 modem
supports the DTE modes Standard Async, High-speed and synchronous.

The
MIL-STD-188-110B is functionally the same as STANAG 4539.
The Performance specification differs insofar as:
- The performance requirements
for a Ricean channel are omitted.
- Design objectives are omitted
- The STANAG 4203 filters are
omitted from the HFCS for this test.

STANAG 4285
The STANAG 4285 waveform does not have embedded AUTOBAUD fields. Thus
the transmitter and receiver need to be set up to the desired data rate
and interleaver at both ends of the link. The setting used in one
direction of the link by no means need to be the same as in the reverse
direction.
For this waveform the
RM6 modem
supports the DTE modes Standard Async, High-speed and synchronous.
The STANAG 4285 waveform includes TEX
capability. Cancellation of up to 4 tones is possible. Table 7 and Table
8 below summarise the waveform OTA settings.

transmitter and receiver need to be set up to the desired data rate and
interleaver at both ends of the link.
For this waveform the

supports the DTE modes Standard Async, High-speed and synchronous.

The STANAG 4415 is also known as the very robust 75 bps HF data
waveform. It will operate effectively almost 11 dB below the noise floor
in a noise dominated environment.

capability. This waveform is also included as the 75 bps rate of STANAG

MIL-STD-188-110B Appendix F (ISB
operation)
The rates specified in MIL-STD-188-110B Appendix F are for ISB operation
and require an ISB capable radio. These rates of this waveform family
include 9600, 12800, 16000 and 19200 bps (all coded). This waveform is
suitable for very high data rate traffic under ground-wave or benign HF
propagation conditions.
For this waveform the
RM6 modem
supports the DTE modes Standard Async, High-speed and synchronous.
Table 17 represents the data rates for
MIL-STD-188-110B Appendix F. |
