  • Patent number: 11894920
    Abstract: Apparatuses that provide for secure wireless communications between wireless devices under cover of one or more jamming signals. Each such apparatus includes at least one data antenna and at least one jamming antenna. During secure-communications operations, the apparatus transmits a data signal containing desired data via the at least one data antenna while also at least partially simultaneously transmitting a jamming signal via the at least one jamming antenna. When a target antenna of a target device is in close proximity to the data antenna and is closer to the data antenna than to the jamming antenna, the target device can successfully receive the desired data contained in the data signal because the data signal is sufficiently stronger than the jamming signal within a finite secure-communications envelope due to the Inverse Square Law of signal propagation.

  • Patent number: 11894947
    Abstract: A GRE tunnel is configured between multiple computing devices of a distributed cloud computing network and a single origin router of the origin network. The GRE tunnel has a first GRE endpoint that has an IP address that is shared among the computing devices of the distribute cloud computing network and a second GRE endpoint that has a publicly routable IP address of the origin router. A first computing device receives an IP packet from a client that is destined to an origin server. The first computing device processes the received IP packet and encapsulates the IP packet inside an outer packet to generate a GRE encapsulated packet whose source address is the first GRE endpoint and the destination address is the second GRE endpoint. The GRE encapsulated packet is transmitted over the GRE tunnel to the single origin router.

  • Patent number: 11894949
    Abstract: Some embodiments establish for an entity a virtual network over several public clouds of several public cloud providers and/or in several regions. In some embodiments, the virtual network is an overlay network that spans across several public clouds to interconnect one or more private networks (e.g., networks within branches, divisions, departments of the entity or their associated datacenters), mobile users, and SaaS (Software as a Service) provider machines, and other web applications of the entity. The virtual network in some embodiments can be configured to optimize the routing of the entity's data messages to their destinations for best end-to-end performance, reliability and security, while trying to minimize the routing of this traffic through the Internet. Also, the virtual network in some embodiments can be configured to optimize the layer 4 processing of the data message flows passing through the network.

  • Patent number: 11894954
    Abstract: A receiver device according to an embodiment includes a equalizer, a sampler, and a controller. The equalizer receive a first signal. The equalizer boosts the first signal to output a resultant as a second signal. The sampler samples the second signal. The sampler outputs a sampling result of the second signal as a first digital signal. The controller executes adaptive processing for adapting an amount of boost of the first signal. In the adaptive processing, the controller is configured to: adjust an amount of boost for the equalizer based on inter-symbol interference of a part in the first digital signal, the part matching a data pattern of a set pattern filter; and dynamically change a pattern filter to be set according to the amount of boost for the equalizer.

  • Patent number: 11894955
    Abstract: Embodiments of the present disclosure relate to a method and system for transmitting a sequence with low peak-to-average-power-ratio (PAPR). A communication system receives control data. A transmitter of the communication system comprises a plurality of sequences which are associated with the control data in the transmitter. The transmitter selects a sequence from the plurality of sequence. The selected sequence is rotated, pre-coded for generating pre-coded sequence. DFT is applied on the pre-coded sequence for generating frequency domain signals. The frequency domain signals are processed and corresponding waveform is transmitted to a receiver of the communication system. The receiver receives the waveform and is processed to extract the sequence from the waveform. The receiver correlates the extracted sequence with plurality of sequences stored in receiver memory to detect the control data. The generated waveform has low PAPR.
