  • Publication number: 20210144033
    Abstract: Systems, devices, and methods of the present invention facilitate secure communication by altering the set of symbol waveforms that may be in use in particular symbol times defined herein as Symbol Waveform Hopping. SWH may be enabled by selecting two or more modulation formats that have sufficiently comparable communication performance (e.g., occupied bandwidth and signal power efficiency), but characterized by symbol waveform alphabet that include different symbol waveform, so that the overall transmission/communication performance of data stream in a signal transmission channel of the system is not significantly affected by switching between modulation formats. Some or all of the symbol waveforms in each alphabet may not be present in other alphabets.

  • Patent number: 10979271
    Abstract: A method for waveform bandwidth compression (WBC) and a system configured to perform the method, which may include the steps of: processing information to produce an input sequence of real-valued amplitude signals; fitting a polynomial to the input sequence covering at least one transmission time interval; converting the polynomial to a transmission signal comprising a sum of sinusoids with continuously time-varying amplitudes; transmitting the transmission signal; and receiving the transmission signal as a time-amplitude sequence. This method may significantly improve the spectral efficiency of existing transmission systems, while at the same time requiring only minimal modification to traditional radio architecture design.

  • Patent number: 10972322
    Abstract: Systems, devices, methods, and computer readable medium for transmitting data using polynomial-based signals. Data may be represented as a message polynomial and convolved with a reference polynomial to generate a transmission polynomial. The transmission polynomial may be converted in a set of sinusoidals with continuously-varying amplitude in a plurality of frequencies prior to transmission of a signal to a receiver. Following transmission, the signal is received and the amplitude values are mapped into bit sequences to recover the data.

  • Patent number: 10686635
    Abstract: A method for communicating using polynomial-based signals. In such a method, a set of basis polynomial functions used to generate waveforms may be identified, wherein each of the basis polynomial functions in the set of basis polynomial functions is orthogonal to each of the other basis polynomial functions in the set of basis polynomial functions in a coordinate space. The set of basis polynomial functions may be combined into a message polynomial. The message polynomial may be convolved with a reference polynomial to produce a transmission polynomial. From the transmission polynomial, a sequence of amplitude values may be generated. Finally, a signal may be transmitted based on the sequence of amplitude values, which may be further modified based on, for example, instantaneous spectral analysis. In some embodiments, orthogonal polynomials may include Chebyshev or Cairns polynomials.
