In this paper, we propose a novel multi-carrier transmission scheme as an alternative approach to orthogonal frequency division multiplexing (OFDM) in order to mitigate intercarrier interference (ICI). In the proposed scheme called block-filtered multi-carrier (BFMC), a filtering operation applied to a group of consecutive subcarriers in order to reduce the effect of sidelobe interference on the immediate adjacent subchannels and thereby eliminate ICI . Moreover, we consider the uplink of coordinated multipoint (CoMP) schemes, where a number of adjacent base stations (BSs) sends the received signals from all user equipments (UEs) to a CoMP central unit (CCU) to jointly process and reduce inter-cell interference. Furthermore, we investigate the impact of carrier frequency offset (CFO) on the performance of the proposed system and compare the results with the performance of cyclic prefix based orthogonal frequency division multiplexing (OFDM) system.

  • 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 ...
