  • Detecting intermodulation in broadband communication affecting receiver sensitivity
    Patent number: 10897341
    Abstract: The present invention provides methods, apparatuses and a program relating to detecting passive intermodulation in broadband communication. The present invention includes transmitting, at a base station, a first signal at a first centre frequency and a second signal at a second centre frequency with a predetermined transmit power, capturing, at the base station, received signal at a reception frequency, obtaining, at the base station, a delay between the transmitted signal and a passive intermodulation caused received signal.
    Type: Grant

    Date of Patent: January 19, 2021
    Assignee: Nokia Solutions and Networks Oy
    Inventors: Marko Fleischer, Michael Kronwald, Thomas Klink, Jan Hellmann, Eric Koenig
  • Distance to VSWR fault measurement
    Patent number: 9755673
    Abstract: The present invention addresses apparatuses, methods and computer program product for providing improved distance to fault measurement for voltage standing wave ratio (VSWR) on antenna line in networks. An embodiment of the present invention comprises the steps of transmitting a signal to a line to be tested, capturing a forward signal of the signal, capturing a reverse signal of the signal, separating the reflection of the signal in time domain via cross correlation of the forward signal and the reverse signal, and detecting a distance to fault in the line by searching and processing maximum peak position of the captured and separated signals.
