A review of baseband modulation techniques intended for use in high-speed electrical interconnects is presented. A general framework is developed and used to compare the performance of traditional baseband formats and partial response coding. A special focus is placed on spectral characteristics suitable for the high-speed electrical interconnects. For that reason multiple classes of partial response signaling are evaluated to shape power spectral density. This unified treatment is extended to multilevel modulation formats. A comparison between symbolby- symbol and maximum-likelihood detection schemes is made with a conclusion that the latter can efficiently complement or replace forward error correction in partial response systems. A complexity analysis shows that significant simplifications can be done in the detection process without drastically impacting the error ratio.

  • 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 ...
