  • Second order intercept point (IP2) calibration for wireless receivers
    Patent number: 9998242
    Abstract: IP2 calibration efficiency can be improved by passing the calibration signal through the transceiver's duplexer instead of inserting the calibration signal directly onto transceivers receive circuit. Passing the calibration signal through the duplexer may reduce IP2 calibration periods for transceivers having less-permeable duplexers, or duplexers that provide better than average separation between the RX and TX circuits. IP2 calibration inefficiencies can also be reduced by using a binary-like search when computing the in-phase and quadrature-phase path correction coefficients of the IP2 correction code.

  • VIDEO STREAM NETWORK CODING IN INFORMATION CENTRIC NETWORKS
    Publication number: 20180159915
    Abstract: The disclosure relates to technology for network coding a video stream in an information centric network. A network node breaks a media segment (e.g., a video segment) into chunks. The chunks for one media segment are then encoded into network encoded chunks, each of which may be a linear combination of the chunks for that media segment. Thus, a number of network encoded chunks for a media segment are generated. These network encoded chunks may be provided to a client in response to a request for content in an information centric network (ICN). When the client receives enough network encoded chunks, the client decodes them to produce the original chunks for that media segment. The client may perform bit-rate adaptation based on the time it takes to receive a media segment. The client may view the communication interfaces as a logical communication link upon which to perform rate adaptation.
