IEEE Journal on Selected Topics in Signal Processing, 2012
The main contribution of this paper is the insight that the transmitters' knowledge of channel coherence intervals alone (without any knowledge of the values of channel coefficients) can be surprisingly useful in a multiuser setting, illustrated by the idea of blind interference alignment that is introduced in this work.

Interference alignment in MIMO interference relay channels
2012 IEEE Wireless Communications and Networking Conference (WCNC), 2012 The degrees of freedom (DoF) has been recognized as a powerful metric to characterize the capacity of interference channels in the high signal-to-noise (SNR) region. In this paper, by utilizing linear interference alignment, we investigate the DoF of multiple-input and multiple-output (MIMO) interference relay channels without symbol extensions.

Retrospective Interference Alignment Over Interference Networks
IEEE Journal on Selected Topics in Signal Processing, 2012Maddah-Ali and Tse recently introduced the idea of retrospective interference alignment, i.e., achieving interference alignment with only outdated (stale) channel state information at the transmitter (CSIT), in the context of the vector broadcast channel.

Interference Alignment for Cellular Networks
2008 46th Annual Allerton Conference on Communication, Control, and Computing, 2008 In this paper, we propose a new way of interference management for cellular networks. We develop the scheme that approaches to interference-free degree-of-freedom (dof) as the number K of users in each cell increases. Also we find the corresponding bandwidth scaling conditions for typical wireless channels: multi-path channels and single-path channels ...

Interference Alignment for Physical Layer Security in Multi-User Networks With Passive Eavesdroppers
IEEE Transactions on Information Forensics and Security, 2023We investigate the physical layer security (PLS) in multi-user interference networks. In particular, we consider secure transmission from a legitimate source (Alice) to a legitimate destination (Bob), coexisting with multiple passive eavesdroppers (Eves),

RIS-Assisted NOMA With Interference-Cancellation and Interference-Alignment Scheme
IEEE Communications Letters, 2023Reconfigurable intelligent surface (RIS) is a cost-effective method to enhance the end-to-end wireless channel. Meanwhile, Non-Orthogonal Multiple Access (NOMA) improves the overall spectral efficiency, connectivity and latency by allowing different ...

Joint Interference Alignment and Power Control for Dense Networks via Deep Reinforcement Learning
IEEE Wireless Communications Letters, 2021This letter proposes a joint interference suppression scheme in heterogeneous networks (HetNets) with dense small cells (SCs) and users. Different from the majority of existing studies, we adopt the co-tier intra-cell interference alignment (IA), while ...
