Press Release

CMX7262 chip 


Elbit Systems (Israel) is an Israel-based international defense electronics company engaged in a wide range of programs throughout the world.

It is a large manufacturer and integrator of advanced, high-performance defense electronic and electro-optic systems: 

  • military aircraft and helicopter systems; 
  • helmet mounted systems; 
  • commercial aviation systems and aero structures; 
  • unmanned aircraft systems; 
  • naval systems; 
  • land vehicle systems; 
  • command, control, communications, computer and intelligence (C4I) systems; 
  • electro-optic and countermeasures systems; 
  • homeland security systems; 
  • electronic warfare (EW) and signal intelligence (SIGINT) systems; etc.

Since 2007, Elbit has been a regular customer of DSPINI. We performed several projects, including four large DSP software development/customization projects. Elbit has acquired licenses for DSPINI's low-bit rate vocoders, echo cancellers, noise suppressors, and other DSP software.

Project 1

“When we chose DSPINI among a few DSP teams/suppliers for our project, we were not entirely certain of its success since we hadn't worked with DSPINI before. However, the high level of professionalism and experience displayed by the DSPINI team during the project, along with the exceptional results we have achieved, convinced us that DSPINI is a reliable team with truly unique technologies. They have demonstrated their capability to undertake complex projects with the utmost reliability and quality.” 

Zeev Schwartz, Senior Director of Digital Communication/Tactical Radio Business line at Elbit Systems and C4I - Tadiran


The project spanned several months and comprised multiple stages, which involved reviews, meetings, and acceptance tests conducted in DSPINI's premises.


Unique DSP software was developed, and a range of high-quality proprietary products were customized and licensed, specifically:

  • DSP components for the PNR (Private Network Radio) and Intercom System.
  • Vocoders tailored to unique frame sizes and bit rates, designed specifically to withstand noisy channels and challenging acoustic environments with high robustness.
  • Noise suppressors, echo cancellers, and other DSP products that offer exceptional technical characteristics and superior quality.

Project 2

“We required a high-quality vocoder for our Intercom system, and DSPINI delivered a unique vocoder, based on their SPR+ technology. It excels in voice quality, robustness, and performance on the C55 platform. We are grateful for their high level of professionalism and expertise for such outstanding results.” 

Zeev Schwartz, Senior Director of Digital Communication/Tactical Radio Business line at Elbit Systems and C4I - Tadiran


The project encompassed the customization of our SPR vocoder technology to meet the specific requirements of Elbit. During the Feasibility Study stage, two different vocoders were proposed. The best vocoder was optimized for the C55 platform and delivered with the appropriate license to Elbit.

Project 3

“Thank you for delivering exceptional results in such short time. Your commitment to quality and support remains truly outstanding.” 

Tomer Varona, HF/VHF/UHF Radio Systems Projects Director

Project / Product:

SPR vocoder with enhanced robustness for usage in very challenging conditions of a noisy radio channel has been delivered. Unique FEC (Forward Error Correction) with UEP (Unequal Error Protection) and a smart recovery system were used to achieve such a high level of robustness.

Project 4

“Our requirements were very difficult to fulfill, yet the result has exceeded our expectationsExceptional work!”

Tomer Varona, HF/VHF/UHF Radio Systems Projects Director


The project was executed in multiple stages and involved substantial modifications to all previously delivered DSP modules.


The DSP software with unique features was customized and licensed. First, a Noise Suppressor for Speech Enhancement, capable of working with very short frame sizes, such as:

  • 12.25 ms
  • 10 ms
  • 6.125
  • and even 3.0625 ms
DSPINI is the only company in the market that delivers Noise Suppresors with such low delay.
Project 5

“This is what keeps us coming back to DSPINI time and time again. Working with your innovative and professional team is always a pleasure. Thank you for the outstanding results.” 

Tomer Varona, HF/VHF/UHF Radio Systems Projects Director

Project / Products:

Low Bit Rate vocoders with unique features, based on SPR technology, were customized and delivered with the appropriate licenses.
