Recommending channel characteristics for V2X communication has the distinct advantage of pre-conditioning the waveform at the transmitter to match the expected fading profile. The difficulty lies in extracting an accurate model for the channel, especially if the underlying variables are uncorrelated, unobserved and immeasurable. Our work implements this prescience by assimilating the Channel State Information (CSI), obtained as a feedback from vehicles, over time and space to adjust the modulation vectors such that the channel impairments are significantly diminished at the receiver, improving the Bit Error Rate (BER) by 96% for higher order modulations. To account for the multivariate, non-stationary V2X channel, a tensor decomposition and completion approach is used to mitigate the effects of sparsity and noise in the CSI measurements.

Decoupling the control and data planes has become synonymous with Software Defined Networking (SDN). This paradigm introduces a multitude of benefits to modern networks – such include reduction of management complexity and cost, modularity, optimized utilization, and isolated innovation. The strict requirements of next generation mobile networks can be summarized by a set of Key Performance Indicators (KPIs). Peak data rates and network latency KPIs for 5G have driven the need for researchers to turn their focus to the mobile backhaul. This paper identifies the challenges faced by next generation mobile networks and investigates state-of-the-art solutions implementing SDN at the backhaul level. In addition, it presents five distinct categories of SDN-enabled solutions and discusses their effectiveness in meeting such KPIs. Mobility management, joint Radio Access Network (RAN) intelligence, multi-tenancy, caching, and traffic monitoring are areas where SDN could prove to be a powerful technology enabler in backaul networks.

In the current paper we proposed a Multiplicity codes based adaptive PIR protocol that is beneficial for multi cloud platform services featured by a high variability in terms of resources, as servers availabilities and storage capacity. Besides the proposed protocol can handle occasional updates when database size varies, with guaranteed minimal communication overhead compared to the trivial case of PIR.

Human users of future smart ubiquitous systems will be immersed in a technology-laden environment; thus, it is important to understand how users interact effectively with these systems. This paper proposes an activity analysis model to study different affective states associated with different user interactions while performing the sentiment analysis of the user. A typical scene in the context of a smart home has been analyzed. The results of the analysis show that this model can be suitably applied by designers to identify and enhance different interface designs for improving user experiences and enhancing human-computer interactions in different contexts.

This paper analyzes physical downlink control channel (PDCCH) for 5G New Radio (NR) technology defined as part of Rel-15 3GPP physical layer specifications. The particular combination of design elements makes NR PDCCH unique compared to the PDCCH or EPDCCH designs in LTE. We focus on the physical aspects of NR PDCCH structure and provide an in-depth summary of the design considerations, analysis of novel search space (SS) design options to better balance the PDCCH blind decoding (BD) and channel estimation capabilities, and performance evaluation of various transmission schemes and configurations supported by NR PDCCH. This study attests the flexibility and robustness of NR PDCCH design in addition to potential further enhancements for the scenarios with more stringent reliability requirements, e.g., URLLC applications.

We examine the effects of introducing relays into millimeter-wave residential access networks. Single-hop networks require professional customer equipment installation on rooftops in order to obtain the necessary line-of-sight properties. An alternative is a two-hop approach with relays that each serve multiple homes. In this case the final access links do not need to be line-of-sight (and so we can utilize customer-installed equipment). We evaluate multiple configurations and show that the rate distribution with relays can be close to the macro-only rate distribution, even in the case that the single-hop macro-only scenario is line-of-sight.

This paper presents CHRONOS, a Cloud based Hybrid RF-Optical Network Over Synchronous Links. The primary goal of this project is to design, build and maintain a multi-node, heterogeneous, wideband, scalable, hybrid and synchronous Cloud Radio Access Network (Cloud RAN or C-RAN), specifically to support emerging applications requiring both THz-optical and conventional sub-6GHz technologies like Wi-Fi and cellular networks. The novelty of the testbed is in enhancing the core capabilities of C-RAN in multiple directions by integrating synchronous RF and Optical links that is not considered for contemporary C-RAN deployments. The long term goal of this project is to utilize the testbed to enable practical research in wireless and optical communication with emphasis on new hardware and software architecture for signal processing. In this paper, we present the design, implementation and initial results of CHRONOS, in an indoor setting, with a clear path to a scalable and real-time network. Our results show synchronous reception across multiple edge nodes while achieving an aggregate bandwidth of 108Mbps using 20MHz OFDM waveform in each RF and optical paths.

We consider the performance implications of using self-backhaul in a millimeter wave (mmWave) wireless network. In a self-backhauled network some nonanchored basestations route their traffic through another anchored basestation rather than utilize an expensive wired backhaul. Self-backhaul is particularly attractive in the mmWave context since we can form narrow beams that reduce the interference due to the backhaul links.In this work we study how interference and load affect the overall performance of self-backhauled networks and we examine which network parameters determine whether self-backhaul is beneficial. We demonstrate that highly directional beams and a steep path loss function improve the tradeoffs associated with self-backhaul. We also develop a scaling law that allows us to easily estimate the self-backhaul capacity.
