Astrapi’s NSF research proposal, “Spiral Polynomial Division Multiplexing (SPDM),” will investigate powerful new radio synchronization techniques.

Astrapi Corporation is pleased to announce that the company’s National Science Foundation Phase I Small Business Innovation grant proposal was accepted for funding. Astrapi’s proposal, “Spiral Polynomial Division Multiplexing (SPDM),” is an embodiment of its spiral-based signal modulation technology. A critical and limiting problem for any communication system is synchronization between the transmitter and receiver. SPDM has shown considerable promise for supporting very precise and low-overhead synchronization. SPDM also provides a structured way to dramatically increase the flexibility of symbol waveform design and to use this additional flexibility to address key problems in telecommunications. In addition to robust synchronization, potential benefits of SPDM include coherent interference rejection, increased spectral efficiency, and reduction of peak to average power (PAPR). This project will rigorously investigate SPDM synchronization (Follow this link to the NSF Awards page: http://www.nsf.gov/awardsearch/showAward?AWD_ID=1621082&HistoricalAwards=false)

“This NSF-funded project represents an important step in the introduction of SPDM to the communications marketplace”, said Dr. Jerrold Prothero, Astrapi Founder and CEO. “We look forward to working with our partners, Dr. fred harris, San Diego State University and L-3 Communications West, on this project. SPDM has the potential to provide dramatic improvements in how communications companies can deal with synchronization, interference and PAPR-related issues. The broad applicability of SPDM in Cellular (4G-LTE), Wireless Local Area Network (802.11 a/g/n), Digital Audio and Terrestrial Television Broadcasting (DAB, DVB-T), Cable Service (DOCSIS 3.1), Digital Subscriber Line (VDSL and VDSL2), DVB-S2 industry networks reflects the broad potential market for SPDM-based systems.”

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 available at a lower cost.

ABOUT the National Science Foundation
The National Science Foundation (NSF) is an independent Federal agency created by the National Science Foundation Act of 1950, as amended (42 USC 1861-75). The Act states the purpose of the NSF is "to promote the progress of science; [and] to advance the national health, prosperity, and welfare by supporting research and education in all fields of science and engineering."

NSF funds research and education in most fields of science and engineering. It does this through grants and cooperative agreements to more than 2,000 colleges, universities, K-12 school systems, businesses, informal science organizations and other research organizations throughout the US. NSF receives approximately 55,000 proposals each year for research, education and training projects, of which approximately 11,000 are funded. In addition, the Foundation receives several thousand applications for graduate and postdoctoral fellowships.
