User-Centric Interference Nulling in Downlink Multi-Antenna Heterogeneous Networks

open access: yes, 2016
In heterogeneous networks (HetNets), strong interference due to spectrum reuse affects each user's signal-to-interference ratio (SIR), and hence is one limiting factor of network performance. In this paper, we propose a user-centric interference nulling (

Space-Time Signal Design for Multilevel Polar Coding in Slow Fading Broadcast Channels

open access: yes, 2019
Slow fading broadcast channels can model a wide range of applications in wireless networks. Due to delay requirements and the unavailability of the channel state information at the transmitter (CSIT), these channels for many applications are non-ergodic.
