Secured green communication scheme for interference alignment based networks

Journal of Communications and Networks, 2020
In this paper, a new security and green communication scheme is proposed to the interference-alignment (IA) based networks. To achieve a secured communication, full-duplex receivers are utilized to transmit artificial noise (AN). Both the signals and the

Partial interference elimination based retrospective interference alignment scheme in the downlink MIMO broadcast channel

Tongxin xuebao, 2021
For interference networks, the degree of delay (DoD) was proposed to quantify the information delay among traditional interference alignment (IA) schemes.It indicated that networks suffer from the issue of latency caused by IA schemes.Herein, for the ...

Retrospective Interference Alignment for the MIMO interference broadcast channel [PDF]

2015 IEEE International Symposium on Information Theory (ISIT), 2015
The degrees of freedom (DoF) of the multiple-input multiple-output (MIMO) Interference Broadcast Channel (IBC) with 2 cells and 2 users per cell are investigated when only delayed channel state information is available at the transmitter side (delayed CSIT).

Evidence‐Informed Multidisciplinary Consensus Guidance for the Psychosocial Care of Adolescents With High‐Risk Cancer: Recommendations From the Italian Association of Pediatric Hematology and Oncology

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Adolescents with high‐risk cancer face complex developmental, psychosocial, and ethical challenges that extend beyond disease‐directed treatment. Although international recommendations exist for communication, psychosocial care, pediatric palliative care, survivorship, and shared decision‐making, these have largely evolved within ...
