Title: What is the Role of MIMO Beyond LTE: Massive? Coordinated? mmWave?
Professor Robert W. Heath Jr, PhD.
The University of Texas at Austin

Abstract: MIMO communication exploding again – this time in the number of antennas. Massive MIMO brings hundreds of antennas at the base station serving tens of uses ala multiuser MIMO. Coordinated MIMO coordinates dozens of antennas at different base stations to reduce the effects of interference. mmWave MIMO uses large arrays at base station and user equipment to serve multiple users with narrow beams and lots of spectrum. This talk will explain key features of each technology and then will provide comparisons of coverage and capacity using a mathematical framework built around stochastic geometry.

Title: Will future wireless systems be cooperative, massive, or messy?

Professor Angel Lozano, PhD.

Vice-Rector for Research, Universitat Pompeu Fabra.



Abstract: Motivated by fundamental information-theoretical results, MIMO (multiple input multiple output) communication emerged with force in the late 1990s and, in record time, made its way into a central feature of commercial wireless systems. We will –briefly– review how MIMO has grown and developed, and assess its current standing. Then, we will examine the challenges faced by wireless systems today and, in particular, by macro-cellular systems: the foundation of the wireless revolution. We will see how MIMO principles are being applied to tackle those challenges, and discuss various competing approaches. Finally, we will speculate on what the future might hold for macro-cellular systems, and on their potential roles in the complex wireless communications landscape that is shaping up.

Title: Dualization of Signal Recovery Problems
Prof. Dinh Dũng
Information Technology Institute, Vietnam National University, Hanoi, Vietnam

Abstract: Over the years, several structured frameworks have been proposed to unify the analysis and the numerical solution methods of signal (including image) recovery problems. In convex optimization, duality theory can sometimes lead to simpler solution methods than those resulting from direct primal analysis. We propose an approach of the principle of convex duality which is applied to a class of composite variational problems arising particularly in signal recovery. These problems are not easily amenable to solution by current methods but they feature Fenchel–Moreau–Rockafellar dual problems that can be solved by a forward-backward splitting algorithm. The proposed algorithm produces simultaneously a sequence converging weakly to a dual solution, and a sequence converging strongly to the primal solution. Our framework is shown to capture and extend several existing duality-based signal recovery methods and to be applicable to a variety of new problems beyond their scope.

Title: On the Performance of Cognitive Underlay Multihop Networks with Imperfect Channel State Information
Vo Nguyen Quoc Bao, Ph.D
Posts and Telecommunications Institute of Technology (PTIT)

Abstract: In this talk, I propose and analyze cognitive multihop decode-and-forward (DF) networks in the presence of interference due to channel estimation errors. To reduce interference on the primary network, a simple yet effective backoff control power method is applied for secondary multihop networks. For a given threshold of interference probability at the primary network, we derive the maximum backoff control power coefficient, which provides the best performance for secondary multihop networks. Moreover, it is shown that the number of hops for secondary network is upper-bounded under the fixed settings of the primary network. For secondary multihop networks, new exact and asymptotic expressions for outage probability (OP), bit error probability (BEP) and ergodic capacity over Rayleigh fading channels are derived. Based on the asymptotic OP and BEP, a pivotal conclusion is reached that the secondary multihop network offers the same diversity order as compared with the network without back off. Finally, I verify the performance analysis through various numerical examples confirming the correctness of our analysis for many channel and system settings and providing new insight into the design and optimization of cognitive multihop networks.
