The limitation of the radio spectrum and the rapid growth of communication applications
make optimal usage of radio resources essential. Cognitive radio (CR) is an attractive …

Interference alignment (IA) is a promising technique to efficiently mitigate interference and to
enhance the capacity of a wireless communication network. This paper proposes a grouping …

As a potential interference management technique, interference alignment (IA) can
enormously improve the system capacity in the future mobile communication networks …

This paper adopts a novel reflection amplifiers surface (RAS) to suppress the co-channel
interference in the spatial domain. The RAS can reflect and amplify the electromagnetic …

Cellular systems that employ time division duplexing (TDD) transmission are good
candidates for implementation of interference alignment (IA) in the downlink since channel …

Aiming at the limitations of the existing Limited Feedback Interference Alignment algorithms,
this paper proposes a direct codeword selection scheme that maximizes the lower-bound of …

In this letter, we explore a limited feedback scheme for meeting the requirements that
different users demand different communication rates. The main idea of this letter is to …

Interference alignment (IA) is an effective scheme for counteracting multi-user interference in
wireless networks. Unfortunately, IA is sensitive to channel-state-information (CSI) …

We consider the problem of secure communications in a MIMO setting in the presence of an
adversarial jammer equipped with nj transmit antennas and an eavesdropper equipped with …

This paper advocates the use of reconfigurable intelligent surface (RIS) in an active manner
to suppress the over-the-air co-channel interference. Different from the commonly used …
