Digital Private Mobile Radio Can Be Available To Everyone
SPR Robust vocoder is suitable ideally for digital Private Mobile Radio (dPMR), thanks to high speech quality and robustness, to low computing complexity and memory usage and to very attractive price.

PENZA, RUSSIA, April 16, 2009 /24-7PressRelease/ -- Digital Private Mobile Radio (like to ETSI TS 102.490) can be available to everyone if will provide high speech quality in any conditions, will have low cost and will operate a long time without battery charge.

SPR Robust 3600 bps vocoder from DSP Innovations Inc. is based on innovative Sinusoidal Pulsed Representation (SPR) model and provides:
- high speech quality (_ 3.2 PESQ )
- high robustness to channel errors (_ 3.0 PESQ in channel with BER = 3%)
- low computing complexity (_ 30 MIPS for TI's C55 DSP)
- low memory usage (_ 15 kBytes of RAM and _ 35 kBytes of ROM)

All these features allow the vocoder operate on very low cost processor chip (for example, on new Piccolo microcontroller (TMS320F2802x) from Texas Instruments), providing high quality, low power consumption and long life of battery, that is ideally suitable for digital Private Mobile Radio.
Moreover, SPR Robust 3600 bps Vocoder is patent-free and royalty-free as well as other proprietary vocoders from DSP Innovations, that becomes attractive for both radio manufacturers and chip makers.
