White Rabbit Absolute Calibration
Authors: Henk Peek, Peter Jansweijer Abstract: White Rabbit (WR) is a widely used implementation to create high accuracy time dissemination networks. Onsite network calibration can be avoided when using absolute calibrated components, which can be freely exchanged withoutrecalibration. Absolute calibration of high accuracy time dissemination network components enables independent developersand/or vendors to exchange their calibrated…

High Accuracy Synchronization for Distributed Massive MIMO using White Rabbit
Authors: Thomas Bigler, Albert Treytl, David Loschenbrand, Thomas Zemen Abstract: Accurate synchronization is a crucial prerequisite for wireless communication systems and in particular for spatially distributed massive multiple-input multiple-output (MIMO) systems which is also used in the upcoming 5G mobile communication standard. Many applications based on MIMO transmission, such as communication systems or beamforming methods,…
