Achievable Rates of Buffer-Aided Full-Duplex Gaussian Relay Channels
( Institute of Electrical and Electronics Engineers Inc. , 2017 , Article)We derive closed-form expressions for the achievable rates of a buffer-aided full-duplex (FD) multiple-input multiple-output Gaussian relay channel. The FD relay still suffers from residual self-interference (RSI) after ... -
Maximum throughput of a secondary user cooperating with an energy-aware primary user
( IEEE Computer Society , 2014 , Conference Paper)This paper proposes a cooperation protocol between a secondary user (SU) and a primary user (PU) which dedicates a free frequency subband for the SU if cooperation results in energy saving. Time is slotted and users are ... -
Novel Quinuclidinone Derivatives Induced Apoptosis in Human Breast Cancer via Targeting P53
( Elsevier , 2017 , Article)Small molecules that can target human cancers have been highly sought to increase the anticancer efficacy, the present work describes the design and synthesis of novel series of five quinuclidinone derivatives (2a-2e). ... -
On the Design of a Relay-Assisted Network
( Institute of Electrical and Electronics Engineers Inc. , 2015 , Article)A relay network composed of a source, a set of relays, and a destination is considered. A queueing framework is proposed, in which each node maintains a buffer to store its incoming traffic. An optimization-based formulation ... -
On the design of relay-assisted primary-secondary networks
( Institute of Electrical and Electronics Engineers Inc. , 2015 , Conference Paper)The use of N cognitive relays to assist primary and secondary transmissions in a time-slotted cognitive setting with one primary user (PU) and one secondary user (SU) is investigated. An overlapped spectrum sensing strategy ... -
Probabilistic band-splitting for a buffered cooperative cognitive terminal
( Institute of Electrical and Electronics Engineers Inc. , 2014 , Conference Paper)In this paper, we propose a cognitive protocol that involves cooperation between the primary and secondary users. In addition to its own queue, the secondary user (SU) has a queue to store, and then relay, the undelivered ...
