Patent number: 10200227Abstract: In a multi-user communication system, a pre-coder in a transmitter comprises a Discrete Fourier Transform (DFT) spreader provides data symbols spread with Fourier coefficients to generate DFT-spread data symbols. An OFDM modulator, such as an inverse-DFT, modulates the DFT-spread data symbols onto OFDM subcarriers to produce a pre-coded OFDM transmission signal. The Fourier coefficients reduce the transmission signal's peak to average power.Type: GrantFiled: December 31, 2016Date of Patent: February 5, 2019Assignee: Genghiscomm Holdings, LLCInventor: Steve Shattil

Publication number: 20190007841Abstract: A system deploys electronic countermeasures against unmanned aerial vehicles (UAVs) that are determined to be a threat. A radio transceiver coupled to at least one antenna detects if radio signals are being communicated between a remote control unit and a UAV. A mitigation engine communicatively coupled to the radio transceiver synthesizes an exploit signal to be transmitted to the UAV, wherein the exploit signal is configured to inject commands into the UAV's navigation system. If the system determines that the UAV is operating in an autopilot mode, it transmits an induce-mode signal that causes the UAVs to switch to a communication mode so the UAV is responsive to the exploit signal.Type: ApplicationFiled: August 13, 2018Publication date: January 3, 2019Applicant: Department 13, Inc.Inventors: Steve Shattil, Robi Sen

Patent number: 10142082Abstract: A pre-coder in a radio transceiver comprises a Discrete Fourier Transform (DFT) spreader that DFT-spreads a block of data symbols to produce DFT-spread data symbols. The spread data symbols are mapped to Orthogonal Frequency Division Multiplexing (OFDM) subcarriers assigned to the radio transceiver for transmission. An OFDM transmitter employs an inverse-DFT to modulate the DFT-spread data symbols onto the OFDM subcarriers to produce a pre-coded OFDM transmission signal. The spreading reduces the OFDM transmission signal's peak to average power.Type: GrantFiled: January 16, 2017Date of Patent: November 27, 2018Assignee: Genghiscomm Holdings, LLCInventor: Steve Shattil

Patent number: 10051475Abstract: A system detects unmanned aerial vehicles (UAVs) and deploys electronic countermeasures against one or more UAVs that are determined to be a threat. A signal detector detects radio signals communicated between a remote control unit and UAV. A feature extractor extracts signal features from the detected radio signals, and a classifier processes the detected radio signals based on its signal features and determines whether the detected radio signals correspond to a known or unknown radio protocol. A threat analyzer determines if a detected UAV is a threat based on at least one of remote-sensing data and classification(s) of the detected radio signals. When a UAV system employs an unknown radio protocol, a mitigation engine synthesizes an exploit based on corresponding extracted signal features. A response analyzer detects a response from the UAV system when an exploit is activated and may adapt the exploit based on the response. In some cases, the exploits can be configured against a UAV in autopilot mode.Type: GrantFiled: September 28, 2016Date of Patent: August 14, 2018Assignee: Department 13, Inc.Inventors: Steve Shattil, Robi Sen

Patent number: 9893774Abstract: Instead of just consuming network resources, client devices create network resources via cooperative subspace processing to increase data bandwidth and expand radio coverage so the network grows dynamically with demand. Server-side cooperative-MIMO provides joint processing for geographically distributed base stations with overlapping coverage areas. A combination of centralized coordination and distributed computing pools and virtualizes base station processing, which reduces complexity, size, and power requirements of base stations to facilitate rapid and inexpensive network deployments. Cooperative subspace coding reduces overhead and transport-layer inefficiencies, and enables each channel to simultaneously employ multiple network paths, even over non-homogeneous networks. Cooperative subspace processing enables a client in a first network to reuse its allocated channels for communicating in another network without interfering with the first network.Type: GrantFiled: May 12, 2015Date of Patent: February 13, 2018Assignee: Genghiscomm Holdings, LLCInventor: Steve Shattil

Publication number: 20170272182Abstract: A radio transmitter adjusts the spectral, amplitude, and/or phase characteristics of its transmissions to defeat radio fingerprinting identification without destroying the content of the transmissions. The transmitter determines a threshold of signal distortion that impedes RF fingerprint identification while providing an acceptable amount of degradation to data transmissions and then synthesizes a distortion of its unique RF fingerprint to impede identification. The transmitter may create RF fingerprint “personalities” to be paired with different radio protocol behaviors and subscriber terminal identification codes (e.g., MAC addresses or SMSIs) for generating different radio identities.Type: ApplicationFiled: June 5, 2017Publication date: September 21, 2017Applicant: Department 13, LLCInventors: Robi Sen, Steve Shattil

Patent number: 9673920Abstract: A transmitter is configured to change its unique radio signature enough to defeat radio fingerprinting identification without destroying the content of the transmissions. The transmitter may be configured for defeating both transient-signal fingerprinting and steady-state fingerprinting. The transmitter may be configured to obfuscate transient detection. The transmitter may continuously vary spectral, amplitude, and/or phase characteristics of its transmissions to defeat radio fingerprinting. The transmitter may pair radio fingerprints with subscriber terminal identification codes (e.g., MAC addresses or SMSIs) for generating different radio identities. The transmitter may measure another transmitter's radio fingerprint, and, compensating for its own radio fingerprint, spoof the measured radio fingerprint.Type: GrantFiled: December 17, 2013Date of Patent: June 6, 2017Assignee: Department 13, LLCInventors: Robi Sen, Steve Shattil
