Short abstract: In conventional decode-and-forward schemes, the relay node discards a message whenever it contains errors, then invoking a retransmission. Yet, in multirelay systems, it is indeed beneficial to have the relays forward any erroneous message to the destination — as long as distributed encoders at the relays and a joint decoder at the destination are properly engineered. This is called lossy-forward relaying. In this talk, a simple, comprehensive, and effective policy is presented for allocating power to an arbitrary number of lossy-forward relays operating in an arbitrary fading environment.

Short Abstract:The propagation in the mmWave band is indeed an exciting topic and properly characterizing it is still a challenge. Whereas many of the researches on this field focus on the large-scale path loss behavior, little attention has been given to the corresponding fading statistics. In this talk, we shall report on the first order statistics of the short-term fading extracted from field measurements conducted at 55-65 GHz in an indoor environment. It is anticipated that general fading models are required in order to correctly characterize the random channel variations.

Palestrante: Antônio Marcos Alberti

Short Abstract: Internet of things (IoT) has been deeply challenging current Internet and emerging architectures, including 5G and Future Internet. Many architectural limitations, such as weak security, data distribution efficiency, provenance and traceability of sources, excessive human intervention, lack of interoperability and service-awareness in devices configuration, have been exposed and called the society attention. We propose a novel service-defined IoT architecture, in which device configurations are a reflex of the real service needs (given by established contracts); combination of ICN benefits with named-services; and perennial identification of IoT devices, services, and data using self-verifiable naming. All integration work has been supported by a convergent architecture called NovaGenesis, demonstrating its viability as an alternative for the current IoT architectures. A proof-of-concept prototype has been implemented in laboratory under real conditions. The experimental results indicate competitive performance in terms of data transfer, memory and CPU consumption. Embedded NovaGenesis has smaller RAM and ROM requirements when compared to a similar RPL + 6LowPAN stack. Data exchanging has been performed in few milliseconds in a local area network. In this talk, future Internet of things (FIoT) with NovaGenesis is presented and explored.

Palestrante: Dayan Adionel Guimarães

Short Abstract: In centralized cooperative spectrum sensing with decision fusion for cognitive radio applications, the small bandwidth of the report control channel can impose severe limitations to the number of orthogonal transmissions from the secondary users, thus limiting the possibility of the higher cooperation gains brought by an increase in the number of cooperating terminals. The presentation will discuss about ongoing research on a specific form of decision fusion in which the secondary users are allowed do transmit simultaneously and using the same carrier frequency, alleviating the problem of limited control channel bandwidth. Schemes for increasing the energy efficiency of the transmissions will be addressed as well.

He is currently a lecturer and researcher at the National Institute of Telecommunications (Inatel), Brazil.

Palestrante: Gustavo Fraidenraich

Short Abstract: We consider the minimum mean-square error (MMSE) receiver for the generalized frequency division multiplexing system (GFDM) over frequency selective fading channels (FSFC). We derive an approximate probability density function (PDF) for the signal-to-interference-plus-noise ratio (SINR). This expression allows getting a new closed-form expression for the bit error probability for a $M$-QAM modulation scheme. Our results resort on the eigenvalues of a circulant matrix since the entries of $\mathbf{H}$ are complex Gaussian distributed, and the eigenvalues are given as a weighted sum of its entries, the joint eigenvalue distribution is also Gaussian. Comparisons of the simulated and analytical results validate our formulation and allow a quick and efficient tool to compute the bit error rate for the GFDM system.

Palestrante: Paulo Cardieri

Short Abstract: Device-to-device communication (D2D) has been investigated as one of the techniques to be employed in 5G cellular systems, due to its potential to enhance spectral and energy efficiencies. One possible strategy to implement D2D communication is based on allowing D2D terminals to opportunistically access the channel allocated to users of a conventional cellular network. In this so-called underlay mode of operation, both classes of users (D2D and cellular) cause interference to each other, leading to issues related to the intrinsic interaction among users. In this presentation, we report some results related to network stability and interference control by packet retransmission. We first consider the scenario in which terminals of both classes are modeled as queues, and packets arrive at the terminals randomly. Necessary and sufficient conditions are established for the stability of an Aloha network. We also show that, in the case of stable networks, the portion of the radio resource allocated to each class is well defined by a simple expression relating its average delay, intensity of traffic, density of terminals, and the minimum acceptable signal-to-interference ratio. Next, we investigate the use of packet retransmission in a D2D cellular underlay network. We derive a formulation that establishes the conditions to guarantee that a given target D2D outage probability is achievable while ensuring that the interference caused by D2D transmissions to the cellular links is below a given maximum acceptable limit.

Short abstract: In multi-cell dynamic time division duplexing (TDD) systems it is possible to adapt the number of uplink and downlink time slots in each cell to the current traffic demands. However, such adaptability leads to an additional type of interference in DTDD networks: the cross-channel interference from transmissions in opposite link directions, i.e., BS-to-BS and UE-to-UE interference. In order to achieve the full potential of DTDD, it becomes important to efficiently deal with the cross-channel interference. In this presentation we discuss about the application of distributed beamforming to the DTDD scenario, considering different optimization techniques, such as interference pricing.

Short abstract: This presentation will introduce a simple and efficient algorithm to generate white samples for the envelope of the alpha-eta-kappa-mu fading model. To this end, capitalizing on results available in the literature, the random number generator is implemented via the acceptance-rejection approach. The goodness-of-fit is objectively measured via the Kolmogorov-Smirnov test. It is also addressed the performance of a digital communications system over the alpha-eta-kappa-mu fading channel in terms of the average bit error rate showing the impact of the fading parameters as an application for the random sequence generator. Theoretical and simulation results are contrasted, validating the accuracy of the generator.

Short abstract: 5G will bring a revolution to the network domain. Compared to previous generations, 5G is expected to provide not only much greater throughput and higher mobility range but also much lower latency, higher reliability, and higher connectivity density. Based on the development of 5G network, Tactile Internet that enables the delivery of remote real-time control and physical haptic experiences is envisioned by many to revolutionize every segment of the society. From PHY design point of view, the tactile internet requires a network that is capable of delivering massive content, massive control and massive resilience at the same time. This imposes big challenges on the PHY design for achieving high data rate, high availability and low-latency control. To address those challenging aspects, the Vodafone Chair in TU Dresden has been very actively working on both theoretical study and demonstrator development of 5G and beyond systems. In this presentation, we will provide a general view and sample some recent results from research teams in the Vodafone Chair. /p>
