Fairness‐Oriented Transmission Schemes for Multiuser MISO Broadcast Channels
Wireless Communications and Mobile Computing, Volume 2022, Issue 1, 2022., 2022 With the increasing number of Internet of Things (IoT), Industry 4.0 (I4.0), and mobile devices, it can be expected that base stations will have to serve more and more clients with a limited number of antennas. For their broadcast channels, nonorthogonal multiple access (NOMA) and blind interference alignment (BIA) are two efficient and commonly ...

Energy Efficiency Strategy for Big Data in Cloud Environment Using Deep Reinforcement Learning
Mobile Information Systems, Volume 2022, Issue 1, 2022., 2022 Big data entails massive cloud resources for data processing and analysis, which consumes more energy to run. The resources and tasks are increasing exponentially in the cloud environment for the processing of big data, which results in an increment in power consumption to run the cloud data center. So, there is always a scope for optimizing the energy

Secure Degrees-of-Freedom of the MIMO X Channel With Delayed CSIT
IEEE Wireless Communications Letters, 2021 In this paper, we study the secure degrees-of-freedom (SDoF) characterization for the multiple-input multiple-output (MIMO) X channel with confidential messages and delayed CSIT. In particular, we propose a transmission scheme, which can be regarded as a generalization of the state-of-the-art scheme without security and with delayed CSIT.
