A Robust Design for BackCom Assisted Hybrid NOMA
Muhammad Fainan Hanif, Le-Nam Tran, Zhiguo Ding +1
Hybrid non-orthogonal multiple access (H-NOMA) is inherently an enabler of massive machine type communications, a key use case for sixth-generation (6G) systems. Together with back…
A Low-Complexity Solution to Sum Rate Maximization for IRS-assisted SWIPT-MIMO Broadcasting
Vaibhav Kumar, Anastasios Papazafeiropoulos, Muhammad Fainan Hanif +2
This paper focuses on the fundamental problem of maximizing the achievable weighted sum rate (WSR) at information receivers (IRs) in an intelligent reflecting surface (IRS) assiste…
A Max-Min Task Offloading Algorithm for Mobile Edge Computing Using Non-Orthogonal Multiple Access
Vaibhav Kumar, Muhammad Fainan Hanif, Markku Juntti +1
To mitigate computational power gap between the network core and edges, mobile edge computing (MEC) is poised to play a fundamental role in future generations of wireless networks.…
A Minorization-Maximization Method for Optimizing Sum Rate in Non-Orthogonal Multiple Access Systems
Muhammad Fainan Hanif, Zhiguo Ding, Tharmalingam Ratnarajah +1
Non-orthogonal multiple access (NOMA) systems have the potential to deliver higher system throughput, compared to contemporary orthogonal multiple access techniques. For a linearly…
Transmit Antenna Selection in Underlay Cognitive Radio Environment
Muhammad Hanif, Hong-Chuan Yang, Mohamed-Slim Alouini
Cognitive radio (CR) technology addresses the problem of spectrum under-utilization. In underlay CR mode, the secondary users are allowed to communicate provided that their transmi…
Computationally Efficient Robust Beamforming for SINR Balancing in Multicell Downlink
Muhammad Fainan Hanif, Le-Nam Tran, Antti Tölli +1
We address the problem of downlink beamformer design for signal-to-interference-plus-noise ratio (SINR) balancing in a multiuser multicell environment with imperfectly estimated ch…
Efficient Solutions for Weighted Sum Rate Maximization in Multicellular Networks With Channel Uncertainties
Muhammad Fainan Hanif, Le-Nam Tran, Antti Tölli +2
The important problem of weighted sum rate maximization (WSRM) in a multicellular environment is intrinsically sensitive to channel estimation errors. In this paper, we study ways…
Fast Converging Algorithm for Weighted Sum Rate Maximization in Multicell MISO Downlink
Le-Nam Tran, Muhammad Fainan Hanif, Antti Tölli +1
The problem of maximizing weighted sum rates in the downlink of a multicell environment is of considerable interest. Unfortunately, this problem is known to be NP-hard. For the cas…
On the Statistics of Cognitive Radio Capacity in Shadowing and Fast Fading Environments (Journal Version)
Muhammad Fainan Hanif, Peter J. Smith
In this paper we consider the capacity of the cognitive radio channel in different fading environments under a low interference regime. First we derive the probability that the low…
Level Crossing Rates of Interference in Cognitive Radio Networks
Muhammad Fainan Hanif, Peter J. Smith
The future deployment of cognitive radios is critically dependent on the fact that the incumbent primary user system must remain as oblivious as possible to their presence. This in…
On the Statistics of Cognitive Radio Capacity in Shadowing and Fast Fading Environments
Muhammad Fainan Hanif, Peter J. Smith, Mansoor Shafi
In this paper we consider the capacity of the cognitive radio channel in a fading environment under a "low interference regime". This capacity depends critically on a power loss pa…
Performance of Cognitive Radio Systems with Imperfect Radio Environment Map Information
Muhammad Fainan Hanif, Peter J. Smith, Mansoor Shafi
In this paper we describe the effect of imperfections in the radio environment map (REM) information on the performance of cognitive radio (CR) systems. Via simulations we explore…
Interference and Deployment Issues for Cognitive Radio Systems in Shadowing Environments
Muhammad Fainan Hanif, Mansoor Shafi, Peter J. Smith +1
In this paper we describe a model for calculating the aggregate interference encountered by primary receivers in the presence of randomly placed cognitive radios (CRs). We show tha…
