  • Patent number: 11356966
    Abstract: Carrier frequency offset (CFO) estimation is effected by transmission of contemporaneous bit patterns, detectable by a receiver. By analysis of periodicity of bit error occurrences at the receiver, a beating period caused by interference between the two transmitters can be identified. From this beating period, a measure of CFO can be obtained.

  • Publication number: 20210396865
    Abstract: A method for locating devices that transmit, backscatter or receive a wireless signal. The method comprising using each of one or more backscatter devices to modulate and backscatter a carrier signal transmitted by a transmitter. Modulating and backscattering the carrier signal generates a backscattered modulated signal comprising a sideband. The method further comprises receiving the one or more backscattered modulated signals with a receiver. At least one of the phase or amplitude of each sideband are used to determine at least one of: the distance between the transmitter and the backscatter device by which that sideband was generated, the distance between the receiver and the backscatter device by which that sideband was generated, and the sum thereof.

  • Patent number: 10462808
    Abstract: Arrangements described herein provide a distributed means of scheduling communications directed towards a sink node from other nodes in a multi-hop wireless network. By listening for other messages assigning schedules to other nodes, each node is able to create its own local record of scheduled transmissions in its area. This allows each node to determine a preliminary schedule. Having said this, the parent node of the node will have additional information regarding the scheduled local transmissions. Accordingly, the node sends the preliminary schedule to its parent node for confirmation that it provides no collisions/conflicts with other scheduled transmissions. As the parent node is involved in the scheduling of each child node, it is better able to determine whether the child nodes are proposing schedules that may conflict with each other.
