Differential signaling schemes are a common approach to achieving higher noise immunity for critical signals in a high-speed digital design. Measurement and modeling of the transmission lines carrying differential signals, however, pose several different challenges that need to be addressed in order to achieve an accurate picture of differential signal transmission in digital system design and ...

[1] Canonical transform (CT) and full-spectrum inversion (FSI) methods can be used in processing radio occultation data to retrieve transmission profiles, which are necessary in addition to bending angle profiles for the retrieval of atmospheric humidity independent of temperature. Low Earth orbiter–low Earth orbiter cross-link occultations with X/K band frequencies can provide transmission dat...

Multiple-input-multiple-output (MIMO) technology uses multiple antennas and advanced signal processing to increase the communication system capacity, reliability data rate without sacrificing energy consumption or RF bandwidth. In some scenarios, MIMO need be designed knowledge of channel state information. One possible solution is differential space–time block coding (DSTBC). Ettus USRPs (Univ...
