DSP center provide scientific researches and practical R&D works
in the following areas of digital signal processing technology:
Theoretical questions of DSP and its applications.
Low bit rate speech coding (vocoders). Design and implementation
of proprietary speech coding algorithms at bitrates: 1.2, 2.4, 4.6
kbps. Implementation standard speech compression algorithms (DSP software
and hardware modules), single- and multi-channel operating modes,
optimization to reduce DSP loading.
Adaptive filtering in the areas of speech enhancement and echo cancellation.
Low bit rate video coding. Video connection with 9.6 kbps bitrate.
Robust channel coding against bit errors in discrete channels.
HF modem algorithms with increased robustness, in-channel synchronization,
and frequency deviation adaptation. Simulation of HF channels in real
