A terahertz-wave communication system directly connected to an optical fiber network is promising for application to future mobile backhaul and fronthaul links. The possible broad bandwidth in the terahertz band is useful for high-speed signal transmission as well as radio-space encapsulation to the high-frequency carrier. In both cases, the low-latency feature becomes important to enhance the ...

Introduction: The exploitation of temporal and spatial diversity can significantly improve communication quality and associated system performance in a rich-scattering wireless environment. This has been demonstrated through proposals for space-time coded modulations over multiple-input multiple-output (MIMO) radio channels which are understood to be very beneficial for high data-rate systems, ...

We present a deep radio-polarimetric observation of the stellar bow shock EB27 associated to massive star BD+43 3654. This is only confirmed have non-thermal radio emission. used Jansky Very Large Array in S band (2 - 4GHz) test whether this synchrotron emission polarised. The unprecedented sensitivity achieved allowed us map even fainter regions shock, revealing that more diffuse steeper and b...

Signal optimization is affected during radio links between a transmitter and a receiver located in adjacent material media with differing optical densities. The optimization is carried out via the automated control theory method. The radio signal obtained after the optimization is coordinated with the two media's electrical characteristics simultaneously; and this enables low power and small an...
