United States Air Force (USAF) awards Astrapi Corporation a Direct-to-Phase II SBIR contract | Texas News

DALAS, January 24, 2022 / PRNewswire-PRWeb / – Astrapi Corporation received its second phase II SBIR contract from the US Air Force’s AFWERX program. The new contract provides support for Astrapi for the delivery of a prototype software-defined radio (SDR). SDR will realize Astrapi’s advanced communication capability – spiral modulation. Spiral modulation addresses congested and contested communication channels, allowing Warfighters to receive more information through a channel using less signal power.

Astrapi continues to make fundamental improvements to the core physical layer of the communications stack. This project complements another SBIR Phase II project focused on Symbol Waveform Hopping (SWH), funded with support from the US Space Force. SWH provides a unique way to securely transmit a signal. Astrapi is currently working with SDR’s hardware partner to demonstrate spiral modulation in a Ka-band radio that is radiation-hardened and suitable for low-Earth orbit (LEO) deployment. The miniature radio will have the ability to process signals in orbit and will be suitable for LEO, MEO and GEO.

“We are very excited to move this application of spiral modulation towards implementation,” said Dr. Gerold Protero, founder and CEO of Astrapi Corporation. “We have a strong, complete partner in Space Micro. And we are facing a significant challenge – spectral efficiency. It is becoming increasingly clear that anyone who controls the spectrum will control the battlefield. Astrapi’s capabilities help achieve this critical advantage. ”

Based on a new summary of Euler’s formula, the basic mathematics of the telecommunications industry, Astrapi has the ability to design signals as a set of complex spirals. This unleashes, for the first time, the ability to make full use of the possibilities of a continuously non-stationary spectrum. The classical theory of channel capacity contains, in the proof of the sampling theorem, an implicit assumption that the spectrum is at least approximately stationary. By violating this assumption, spiral modulation makes it possible to circumvent Shannon-Hartley law, the previous upper limit for spectral efficiency.

FOR Astrapi Corporation

Astrapi provides fundamentally new ways to optimize spectrum usage, ensure signal transmission and measure non-stationary spectrum power. Astrapi is able to improve the trade-off between the four main parameters in telecommunications: bandwidth, signal strength, data throughput and error rate. The resulting efficiency is higher spectral performance with more bits available at a lower cost. Astrapi currently has fifteen patents issued in the United States, with pending ones and international patent coverage. Additional information on http://www.astrapi-corp.com
