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
time.
-
Algorithms for telephony (DTMF detectors and PTSN control signals)
using for computer and Voice over IP telephony.
-
Signal analysis and design of digital filters
-
Speech processing algorithms for digital hearing aids. Algorithm
design and implementation on DSP (in cooperation with Scientific and
Research Institute of Ear, Throat and Nose).
-
Nonlinear signal processing
-
High-quality DSP implementation of offered algorithms
All DSP algorithms are implemented on TI's DSPs, mostly TMS320C54xx,
TMS320C55xx, TMS320C67xx families.
