Channel-Aware 5G RAN Slicing with Customizable Schedulers

This paper focuses on 5G RAN slicing, where the 5G radio resources must be divided across slices (or enterprises) so as to achieve high spectrum efficiency, fairness and isolation across slices, and the ability for each slice to customize how the radio res ...

A Time-Division Multiplexing Signaling Scheme for Low-Power Multi-Drop Memory Links

Yusuf Leblebici, Gain Kim, Kiarash Gharibdoust, Chen Cao

A time-division multiplexing (TDM) digital channel coding scheme for wireline multi-drop interfaces has been proposed. Shaping the TX spectrum to avoid channel frequency notches, the proposed digital TDM signaling reduces inter-symbol interference (ISI) an ...

ECMA-407: New Approaches to 3D Audio Content Data Rate Reduction with RVC-CAL

Marco Mattavelli, Claudio Paolo Alberti, Junaid Jameel Ahmad

Inverse problems have only been known in spatial audio for a very short time; their only solution, called "inverse coding" in literature, is essentially based on time-level modeling. Inverse problems, however, unlike parametric coding, require only an init ...

Towards highest spectral efficiency: Optical sinc-shaped Nyquist pulses generation from rectangular frequency comb

Luc Thévenaz, Camille Sophie Brès, Marcelo Alfonso Soto Hernandez, Mohammad Amin Shoaie, Mohammad Mehdi Alem Karladani

In this paper, we review a method to produce optical sinc-shaped Nyquist pulses with unprecedented quality. The method is based on the synthesis of a rectangular shaped and phase-locked frequency comb from a combination of intensity modulators. The result ...

ECMA-407: A New 3D audio codec implementation up to NHK 22.2

Marco Mattavelli, Claudio Paolo Alberti, Junaid Jameel Ahmad

ECMA-407, the first 3D audio standard worldwide, introduces a new concept of static models to lower bitrate coding, which may be equally applied with channels, channels and objects and Higher Order Ambisonics (HOA). Static models may either operate in time ...
