Astrapi Corporation

Astrapi provides consulting and engineering services to design communication systems tailored to specific needs using spiral-based signal modulation. They offer unique software tools for designing and testing these systems.

Astrapi has developed a simulation model in MATLAB and Simulink to support RF modem design and other system components, producing spiral-based waveform designs.

Astrapi offers engineering support to integrate spiral signals into communication system designs, leveraging their expertise in non-periodic waveforms.

Astrapi provides IP licenses for the use of its spiral modulation technology in R&D and commercial environments.

A transformative technology that increases spectral efficiency by transitioning from periodic to non-periodic signal modulation, allowing for enhanced communication capabilities.

A technique arising from spiral modulation that allows for a more spectrally-efficient representation of waveforms than traditional Fourier transforms.

Astrapi’s patented Spectrum Analyzer arose from our need in telecommunications to accurately and efficiently measure our occupied bandwidth (range of frequencies used by a signal). Traditional spectrum analyzers based on the Fourier transform contain an implicit assumption that the spectrum is at least approximately stationary (constant power in each frequency), an assumption which Spiral Modulation deliberately breaks. Astrapi’s Spectrum Analyzer avoids an assumption that the spectrum is stationary through a novel application of the superheterodyne principle from telecommunications. Since real-world spectra are almost never stationary, the Fourier stationary assumption is a problem for spectral analysis in many fields outside of telecommunications, which are now addressable by the Astrapi Spectrum Analyzer. The stationary limitation of the Fourier transform is well-known. This limitation has led to a vast literature of work-arounds to deal with this short-coming. These work-arounds include Fourier windows, wavelets, Welch’s Method and Bartlett’s Method. What they all have in common is that they are in the nature of attempting to fit a square peg into a round hole. The fundamental problem is intractable, and so one is left to choose among poor solutions.
