International audience; A key drive towards 5G networks is the Cloud Radio Access Networks architecture (C-RAN). It consists in decoupling two main elements composing the base station: The Base Band Unit (BBU) and the Remote Radio Head (RRH), allowin

International audience; Cloud Radio Access Networks (C-RAN) is an evolution in the base station architecture, mainly composed of two elements: The Base Band Unit (BBU) and the Remote Radio Head (RRH). The BBU is a centralized pool of computational re

Modulation design analysis for two-way relay channels

Autor: Hadi Sawaya, Elias Rachid

Publikováno v: EUROCON

This paper deals with the joint modulation relaying (JMR) design for the two-way relay channel where two users exchange information via a half-duplex relay node. We studied in particular the broadcast mode where the relay node combines the bits recei

8-psk combined to regular and irregular symbol based turbo codes

Autor: Hadi Sawaya

Publikováno v: Scopus-Elsevier

This paper deals with pragmatic 8-PSK turbo coded modulations based on a symbol based iterative turbo decoder. Both regular and irregular turbo codes are considered. Results show that the regular scheme can replace the well known turbo trellis coded

Multilevel coded modulations based on asymmetric constellations

Autor: Joseph J. Boutros, Hadi Sawaya

Publikováno v: Proceedings. 2001 IEEE International Symposium on Information Theory (IEEE Cat. No.01CH37252).

This paper deals with multilevel coded modulations (MLC) based on ASK and PSK constellations for the AWGN channel. Under multistage decoding (MSD) and when block partitioning is applied to an asymmetric constellation, we show that the capacity of the
