Washington, D.C. (December 2014) – Astrapi Corporation is pleased to announce that the company was accepted to present Astrapi’s spiral-based modulation at the NAB Labs Future Park showcase. According to NAB Labs, the Future Park is a unique “showcase of advanced projects, presented by NAB Labs that features demonstrations of high-tech media developments in progress, prototypes, and products not yet available for sale, from academic, government, and commercial research laboratories in the United States and around the world.” The showcase will be held April 13-16 at the Las Vegas Convention Center in Las Vegas, NV. Astrapi staff will be on-site to provide demonstrations of its technology and to explain the theory behind spiral-based modulation.

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.

“We are very excited to be accepted to this prestigious event”, said Dr. Jerrold Prothero, Astrapi Founder and CEO. “Astrapi will lead the way as industry migrates from periodic to non-periodic waveform generation. Spiral-based modulation is well-positioned to address the needs of those transmitting large amounts of content in power constrained, noisy environments. The NAB Lab Future Park is perfectly aligned with Astrapi and we are delighted to participate in the event dealing with the next generation of innovation.”

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.
