LPC-10, or LPC10 is a Linear Prediction Voice Vocoder that operates at 2.4 Kb/s.
The United State Federal Government has standardized many digital voice solutions over HF and VHF/UHF using this Vocoder and standardized as FED-STD-1015.
The ANDVT Family of secure voice terminals uses this vocoder for communications.
- So called LPC10 because 10 LP coefficients are used
- Bandwidth: 2.4kbps
- Samples/frame : 180 samples
- Bits/frame: 54 bits
- Frame Size: 22.5ms = 44.44 frames/sec
- Target stream : 8khz sampling rate, 16bit quantization
