  • Patent number: 10848190
    Abstract: Embodiments herein relate to a method performed by a receiving device for handling signalling in a wireless communication network. The receiving device measures a strength, or a complex amplitude, of one or more signals over a signal path to a transmitting device, which measured strength or complex amplitude forms a signal pattern over a time. Furthermore, the receiving device matches the signal pattern with a stored signal pattern and, if the signal pattern matches the stored signal pattern, the receiving device determines whether an object will block the signal path between the receiving device and the transmitting device.

  • Patent number: 10764101
    Abstract: A system and method for waveform modulation includes encoding input digital data at selected phase angles of an unmodulated sinusoidal waveform. The encoding includes selectively reducing a power of the unmodulated sinusoidal waveform at the selected phase angles in accordance with bit values of the input digital data so as to respectively define first, second, third and fourth data notches in the modulated sinusoidal waveform. An encoded analog waveform is then generated from a digital representation of the modulated sinusoidal waveform. The encoding is performed so that energies associated with the first and third data notches are balanced and energies associated with second and fourth data notches are also balanced. Each of the energies corresponds to a cumulative power difference between a power of the unmodulated sinusoidal waveform and a power of the modulated sinusoidal waveform over a phase angle range subtended by one of the data notches.
