Astrapi Corporation is pleased to announce that it has been accepted as a member company of the National Spectrum Consortium (NSC). Astrapi joins over one-hundred other companies dedicated to improving the use of electromagnetic spectrum. Astrapi’s membership will enable the firm to contribute to the NSC’s mission of improving the efficiency of use of the nation’s electromagnetic spectrum for the government and industry.

“Spiral-based modulation should add value to the NSC’s mission,” said Dr. Jerrold Prothero, Astrapi Founder and CEO. “We are delighted to join the Consortium and look forward to developing spiral-based modulation as an enabling technology and working with other member companies.”

Astrapi’s spiral-based signal modulation, for the first time, puts non-periodic signal modulation on a firm theoretical basis. Classical channel capacity theory implicitly assumes that signals are based on periodic functions. Non-periodic signal modulation opens a pathway to dramatically higher spectral efficiency, limited by hardware capabilities rather than solely by available bandwidth and signal-to-noise power ratio. In addition to the usual circular-based combinations of amplitude modulation, frequency modulation, and phase modulation, Astrapi introduces intra-symbol complex amplitude modulation, time reversal, and rotational reversal. Potential applications include improved performance in the presence of phase impairments, for instance due to multipath interference; greater resistance to interference from competing signals; and the ability to work well with power-efficient and cost-effective nonlinear power amplifiers.

ABOUT Astrapi Corporation
Astrapi is the pioneer of spiral-based signal modulation, which opens an unexplored area for innovation at the core of telecommunications. Based on a generalization of Euler’s formula, the foundational mathematics for telecom, Astrapi provides fundamentally new ways to design the symbol waveforms used to encode digital transmissions. By applying new mathematics to signal modulation, Astrapi is able to improve the trade-off between the four fundamental parameters in telecommunications: bandwidth, signal power, data throughput, and error rate. The resulting efficiency translates into higher spectral performance with more bits transmitted at a lower cost. http://www.astrapi-corp.com

ABOUT National Spectrum Consortium
The National Spectrum Consortium has entered into a five year, $1.25 billion, agreement with the U.S. Army Contracting Command-New Jersey (ACC-NJ). Acting on behalf of The Office of the Deputy Assistant Secretary of Defense, the ACC–NJ seeks to collaborate with the NSC to carry out coordinated research and development designed to develop spectrum access technologies enabling improved recognition of spectrum activity, protection of U.S. activity in the electromagnetic spectrum domain, and the ability to relocate/share spectrum when access is needed. This initiative will support possible needs across the government and industry, in alignment with the National Information Technology R&D (NITRD)/Wireless Spectrum R&D (WSRD) Senior Steering Group (SSG) mission to promote collaboration among government, industry and academia. The envisioned collaboration between Industry and the Government will focus on:

  • maturing technologies that assist in improved electromagnetic spectrum awareness, sharing, and use
  • experimentation to better inform the optimal allocation of those technologies for both public and private objectives
  • demonstration of new technologies to increase trust among spectrum stakeholders
  • policy development to ensure technologies don't outpace the appropriate guidance for their best use
