MIKET DSP Solutions provides the following high-quality eXpress DSP (xDAIS © TI) compliant
for building next-generation telephony and tele/video-conferencing plaftorms,
designed for 'C55xx/C54xx DSP archiectures:
- G.167 Acoustic Echo Canceller
is capable of providing perceptually full duplex quality
in above-average sized office rooms when used even in inexpensive speakerphones
with a single omni-directional microphone.
AEC supports echo tails up to 400ms and, in addition, provides up to 15 dB of noise reduction (Ephraim-Malah).
- Line Echo Canceller is optimized
to provide the maximum attainable, fully transparent voice quality
for de-echoing of a PSTN or POTS connection in VoIP / LAN systems with internal delays,
or on a codec end of a telecom switch (20ms echo tail).
Call for a long tail version.
- DTMF Detector
is based on multi-rate signal processing and
advanced short-term spectral analysis methods (MLE-derived)
to ensure superior precision and robustness.
DTMF detector is fully run-time configurable,
takes very low MIPS (0.25...0.35MIPS) on 'C55xx,
supports 13...16ms latency tone relay,
passes all relevants tests,
and gets only 1...5 false hits on 3 hours on BellCore talk-off tests.
- Call Progress Tone Detector
recognizes single- or dual-tones derived
from the standard North American set of tones (350, 440, 480, 620 Hz) and 400 Hz tone.
CPD detector is fully configurable and extendable.
- Caller ID Receiver provides Type I signal detection
according to relevant BellCore specifications.
CLID tolerates high noise levels (BER=10^-4 on SNR=6dB), abnormal level twists,
and very low signal levels (down to -55 dBm).
