Wireless communications are critical for public protection and disaster relief (PPDR) professionals during the emergency operations that follow natural or man-made disasters, scenarios in which both commercial and dedicated terrestrial networks often fail to provide the necessary support. The reason is threefold: they simply get destroyed by the disaster, they cannot sustain the sudden surge […]
Read moreTelecommunication networks often face power outage problems in the natural disaster affected areas. Also, owing to a sudden substantial increase in network traffic loads the battery backup power of the base stations run out quickly and therefore hampering telecommunication services. To overcome this system performance issues, we propose a Long Term Evolution (LTE)-Advanced (LTE-A)-based user […]
Read moreWith the help of digital resources, self-description of smart objects causes some limitation into the input qualities because of the long established physical appearances. Also to realize the capability of objects to understand and recognize the data. If an uninstrumented surface is provided, the object should be able to sense gestures and touches upon the […]
Read moreThis paper deals with the problem of synchronization in networks of heterogeneous agents with common nominal behavior. The agents are modeled as (possibly nonlinear) perturbed versions of a common SISO nominal LTI operator, and they are interconnected via a sparse memoryless interconnection operator, coherent with the communication graph underlying the network. The network is said […]
Read moreThe Internet of Things (IoT) has the strong potential to support a human society interacting more symbiotically with its physical environment. Indeed, the emergence of tiny devices that sense environmental cues and trigger actuators after consulting logic and human preferences promises a more environmentally aware and less wasteful society. However, the IoT inherently challenges software […]
Read moreRecently, the way people consume video content has been undergoing a dramatic change. Plain TV sets, that have been the center of home entertainment for a long time, are losing grounds to Hybrid TV’s, PC’s, game consoles, and, more recently, mobile devices such as tablets and smartphones. The new predominant paradigm is: watch what I […]
Read moreThe correct inference of gene regulatory network plays a critical role in understanding biological regulation in cells and genome based therapeutics. DNA microarray is the most widely used technology for extracting the relationships between thousands of genes simultaneously. Since S-system is based on the rate law, it is considered as a suitable mathematical model for […]
Read moreUltra-low-power design has been a challenging area for design of the sensor front-ends especially in the area of Wireless Body Sensor Nodes (WBSN), where a limited amount of power budget and hardware resources are available. Since introduction of Compressed Sensing, there has been a challenge to design CS-based low-power readout devices for different applications and among all for biomedical signals. Till now, […]

Near-Body Shadowing Analysis at 60 GHz
A numerical model of the fading of a receiver located near the user body at 60 GHz in an indoor environment is presented. The model is based on the indoor channel model IEEE 802.11ad. The results are presented for a receiver located in a zone from 5 to 30 cm away from the body. With the shadowing depending […]

Performance of uplink joint reception CoMP with antenna selection for reducing complexity in LTE-A systems
Coordinated Multi-point (CoMP) transmission and reception is considered as a promising technique to combat inter-cell interference, enhance throughput, improve mobility, reduce handover interruption time, and also to increase spectrum efficiency. In this paper, we investigate and analyze the performance of uplink intra-site joint reception CoMP (JR-CoMP) for LTE-Advanced (LTE-A) systems. Both single user-MIMO (SU-MIMO) CoMP and […]
