Duplex filters in modern base stations are designed as cavity filters, which are expensive and have big dimensions.

The ever-increasing demand for data traffic for future wireless systems poses challenging requirements for 5G wireless communications, such as high spectral efficiency, better interference manageme

One of the key challenges in next generation 5G networks is to deliver Ultra-Reliable Low-Latency Communications (URLLC).

Modern wireless communication networks, particularly the upcoming cellular networks, utilize multiple antennas to improve capacity and signal coverage.

This paper provides an overview of a satellite-based Unlimited Mobile TV system implementing the recently defined Digital Video Broadcast-SH radio interface.

We report on hybrid Si/III­V lasers with adiabatic coupling.

We report a hybrid silicon optical gate based on a silicon waveguide with a III-V gain medium and two vertical gratings couplers.

We propose a novel hybrid silicon-based laser with integrated variable reflectivity mirror. The single-ring laser is tunable over 10 nm with high SMSR.

Massive multiple-input multiple-output (MIMO) systems can attain a high channel capacity and spectral efficiency by using a very large antenna array at the base station (BS).

Galileo satellite navigation system employs as master navigation signal a 10.23 MHz tone generated from several 10MHz atomic clock references.
