  • Publication number: 20210135703
    Abstract: A method and system for providing a cooperative spectrum sharing model that jointly optimizes primary user equipment parameters for improved frequency agility and performance while mitigating mutual interference between the primary user equipment and secondary user equipment. Spectrum sensing is implemented to form a power spectral estimate of the electromagnetic environment (EME) and apply multi-objective optimization to adjust the operational parameters of the primary user equipment to mitigate interference.

  • Patent number: 10564280
    Abstract: A method and apparatus for detecting an object comprising a radio frequency transmitter for transmitting a radio frequency signal towards an object; an acoustic signal transmitter for transmitting an acoustic signal capable of causing intermittent contact of conductive and/or semi-conductive junctions of the object; and a radio frequency receiver for receiving the radio frequency signal after the radio frequency signal is reflected from the object, where the received radio frequency signal has been altered by the intermittent contact of conductive and/or semi-conductive junctions of the object.

  • Patent number: 10564257
    Abstract: A spectrum sensing radar system including a spectrum power sensing module configured to sense electromagnetic signal powers in a plurality of sub-frequencies and generate a sensed power set including a plurality of sensed electromagnetic signal powers corresponding to each of the plurality of sub-frequencies; a multi-objective function module configured to receive the sensed power set and calculate a first objective function for each of the plurality of sub-frequencies, wherein the first objective function includes a power function divided by an empirical measure of interference of the sensed power set to form a signal plus noise objective function for a sub-frequency of the plurality of sub-frequencies, and wherein the power function further includes a peak transmit power of the radar system multiplied by a gain of an antenna of the radar system, multiplied by a wavelength of a carrier of the sub-frequency.

  • Patent number: 10101436
    Abstract: A method for optimizing bandwidth selection of a radar transmission in a frequency bandwidth in which the frequency bandwidth is divided into a plurality of sub-bands having a plurality of different bandwidths. The energy level is measured for each sub-band and a range resolution is also determined for each sub-band. Thereafter, a sub-band is selected in the frequency range where the signal to interference plus noise ratio plus the range resolution is maximum. Thereafter, a radar transmission is transmitted in the selected sub-band with a bandwidth corresponding to the bandwidth of the selected sub-band.
