SPIRIT MIL-STD-188-110B Data Modem software entirely complies with MILSTD-
188-110B (Appendix C) standard and supports data rates from 3200 to
9600 bps (coded rates) and 12800 bps (uncoded) with 6 possible interleavers -
from zero to 8.64 seconds.
SPIRIT MIL-STD-188-110B Data Modem software allows passing digital data
over HF channels on high bitrates.
The modem is capable to work with high-density constellations and high rate
FEC which provides communication at high data rates. It is optimized for use
under severe propagation conditions with very fast fading, high number of rays,
and low SNR. Properties of waveform enable fast and reliable signal
acquisition.
The modem utilizes modern digital processing technologies such as iterative
(turbo) equalization, channel estimation and detection that provide ultimate
performance under extensive range of propagation conditions.
