  • Configurable antenna arrangements
    Patent number: 11569864
    Abstract: An apparatus is provided that includes a set of antenna elements and switching nodes. Each switching node has physical interconnects to a sub-set of the antenna elements for transferring communication signals and the switching nodes have physical interconnects to other switching nodes forming a network of switching nodes for transferring communication signals between switching nodes. The apparatus also includes a controller for controlling operation of switching nodes to control use of the physical interconnects between switching nodes and control creation of different patterns of antenna elements operationally interconnected via multiple operationally interconnected switching nodes.
    Type: Grant

  • Method and Apparatus for Reducing Self Interference
    Publication number: 20140198688
    Abstract: A method, apparatus, and computer program product are provided to reduce self-interference in a transceiver. In the context of a method, a self-interference channel estimate may be determined. A reconstructed interference may further be determined based at least in part on the self-interference channel estimate and a signal to be transmitted and the reconstructed self-interference is caused to be subtracted from a received signal. According to a further embodiment, detection of a desired signal may be disabled while this process is repeated until a residual self-interference is below a threshold, at which point detection of the desired signal may be enabled.
