This paper focused on design single chip of modern micro base station RF front end (included ADCs and DACs) using the system in package (SIP) technology, the chip has features of full band coverage of one receiver, one feedback channel, and one transmitter integrated, which is integrated in two layer stack design, and focused to solve the interlayer RF signal connection, signal crosstalk in micro distance, and heat diffusion issues, which are verified successfully by the test results. And this paper also discusses the applications in design of the advanced base station of Frequency division system (FDD) and time division system (TDD) based on the chip.

  • Sharma S.

5G networks will have to support a set of very diverse and often extreme requirements. Network slicing offers an effective way to unlock the full potential of 5G networks and meet those requirements on a shared network infrastructure. This paper presents a cloud native approach to network slicing. The cloud ...

Based on the physical model of a bulk reflective semiconductor optical amplifier (RSOA) used as a modulator in radio over fiber (RoF) links, the distributions of carrier density, signal photon density, and amplified spontaneous emission photon density are demonstrated. One of limits in the use of RSOA is the lower ...

How to preserve users' privacy while supporting high-utility analytics for low-latency stream processing? To answer this question: we describe the design, implementation and evaluation of PRIVAPPROX, a data analytics system for privacy-preserving stream processing. PRIVAPPROX provides three properties: (i) Privacy: zero-knowledge privacy (ezk) guarantees for users, a privacy bound tighter ...
