This paper presents a novel low power implementation of feed forward equalizer targeted for wireline receivers in high speed SERDES applications. The 3-tap FFE (Feed Forward Equalizer) is configured to cancel precursor and post-cursor ISI. It is implemented by recycling current into a current integrating summer by equally spaced pulse clocks generated using half-rate Rx clock from PLL. Precursor and...
High Resolution Range Profiles (HRRPs) are widely used in the field of Radar Non-Cooperative Target Recognition (NCTR). An exhaustive set of classification algorithms can be found in the scientific literature but it is not common to find the description of the architectures capable of generating range profiles. This work proposes a specific scheme of a 1-D high resolution imaging radar for maritime...
Time mode signal processing (TMSP) is the implementation of analog signal processing functions using the most basic element available, namely, propagation delay. Moreover, a time to digital converter (TDC), an important block of time mode circuits, could be used to convert the time difference between two edges of two signals into a sequence of digital numbers. In this paper, a new time mode SerDes...
Graph mining is widely used in fields like social network analysis. The synchronous vertex-centric frameworks strike better balance between the performance and ease-of-use, so they are widely used in realistic. However, traditional architectures of this type, like the vertex-based push architecture and GAS, are encumbered by high communication costs. In this paper we proposed a new replica-based push...
In mixed-criticality systems, resource management services are required to recognize and fulfill system wide high-level constraints, e.g., end-to-end deadlines. This is not possible through individual resources in isolation. Instead, a system-wide view is necessary which requires system-wide decisions. In the European FP7 project DREAMS, services for system-wide adaptability of mixed-criticality applications...
In this article, we propose low complexity transmitter and receiver architectures for Faster Than Nyquist communications. Both architectures are based on circular convolutions rather than linear convolutions. These circular architectures allow us to consider a turbo-equalization scheme based on linear MMSE equalization. We can consider low-values for the time compression factor without increasing...
Named Data Networking (NDN) is currently a hot research topic in the field of network architecture, and its transport control mechanism is one of the key technologies needed to be studied. Since the transport in NDN network has the characteristic of multi-source, the implicit congestion detection mechanism of the traditional TCP protocol is no longer suitable for the NDN network. In this paper, we...
Universal asynchronous receiver transmitter, abbreviated DART is a integrated circuit used for serial communications over a computer or peripheral device serial port. DARTs are now commonly included in microcontrollers. The universal designation indicates that the data format and transmission speeds are configurable and that the actual electric signaling levels and methods (such as differential signaling...
Many Web services are expected to run with high degree of security and dependability. To achieve this goal, it is essential to use a Web-services compatible framework that tolerates not only crash faults, but Byzantine faults as well, due to the untrusted communication environment in which the Web services operate. In this paper, we describe the design and implementation of such a framework, called...
The Open Distributed Processing Reference Model (ODP-RM) provides viewpoints and abstract infrastructure guidelines that can be used for a basis for enterprise architecture, especially for an inter-enterprise architecture. The ODP-RM does not prescribe methodology for modeling itself, but provides common vocabulary and focus for description. This paper performs a brief analysis of the ODP-RM (and...
Many real-time communication protocols have been studied to guarantee the communication requirements of distributed real-time systems. But, current techniques lack all or most of these requirements specially bounded message delivery time. In this paper we have proposed a Mac layer protocol called RDM+ with concepts similar to Round Data Mailer multi layer protocol. Our simulation results show that...
This paper presents a distributed fermat-point range estimation strategy, which is important in the moving sensor localization applications. The fermat-point is defined as a point which minimizes the sum of distances from three sensors inside a triangle. This point is indeed at the trianglepsilas center of gravity. We solve the problems of large errors and poor performance in the bounding box algorithm...
This paper explores the attributes, layering models and objective functions in cross layer designs for mobile ad hoc wireless networks by taking all the statistical characteristics and constraints from the physical (PHY) layer, media access control (MAC) layer and network (NET) layer into consideration. This paper reviews the entire network optimization across all the PHY/MAC/NET layers. At the PHY...
The ergodic capacity of single input multiple output (SIMO) wireless communication systems over Nakagami-m fading channels is available in the literature for the case of identically independent distributed (i.i.d.) subchannels. However, the non- identically independent Nakagami-m case is more practical and has not been considered in the literature. In this paper, we derive an analytical expression...
