  • Publication number: 20200412595
    Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for communicating signals using a multi-dimensional symbol constellation. In one example, a process for modulating a carrier signal includes the actions of mapping data to symbols of a multi-dimensional symbol constellation that includes at least three dimensions, each dimension of the constellation represented by a respective modulation signal. The dimensions of the constellation include first and second dimensions each of which are represented by respective in-phase modulation values and quadrature phase modulation values of a quadrature amplitude modulation (QAM) signal, and a third dimension represented by a transpositional modulation (TM) signal. The method further includes modulating a carrier signal with the TM signal and the QAM signal.

  • Patent number: 10880149
    Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for modulating and demodulating transpositional modulated (TM) signals. One aspect features a method of modulating a carrier signal that includes the operations of generating a non-transpositional modulation (non-TM) signal from a first data signal, where the non-TM signal has a frequency spectrum that occupies a bandwidth. Generating a TM signal by generating a modulation from a second data signal, and shifting the modulation signal in frequency to an upper or lower sideband in the frequency spectrum of the non-TM signal which lies within the bandwidth of the non-TM signal, and where the power of the first modulated signal is less than a power of the non-TM signal. Combining the non-TM signal with the TM signal on a common carrier signal to provide a combined signal. Transmitting the combined signal.

  • Patent number: 10447340
    Abstract: In a direct sequence spread-spectrum (DSSS) systems, such as CDMA, information is encoded in symbols using phase shift keying or quadrature amplitude modulation. Further, a transmitter applied a selected time shifted lag to each symbol to convey additional information. A receiver detects both the symbol data and the lag value. The receiver can use a hermetic matched filter matrix to identify the lag.
