In this paper, we discuss several Coordinated Multi-Point (CoMP) schemes proposed for LTE- Advanced systems. We investigate their benefits in a multi-antenna beamforming system where multiple cells may share their resources and jointly coordinate their transmissions to improve the performance at cell edge and the overall system capacity. We evaluate the system performance by combining flow-level […]

Second-Order Cyclostationarity-Based Detection of LTE SC-FDMA Signals for Cognitive Radio Systems
In this paper, we investigate the detection of long-term evolution (LTE) single carrier-frequency division multiple access (SC-FDMA) signals, with application to cognitive radio systems. We explore the second-order cyclostationarity of the LTE SC-FDMA signals and apply results obtained for the cyclic autocorrelation function to signal detection. The proposed detection algorithm provides a very good performance under various […]
Read moreBrain-machine interface (BMI) technology has tremendous potential to revolutionize healthcare by greatly improving the quality of life of millions of people suffering from a wide variety of neurological conditions. Radio-frequency identification (RFID)-inspired backscattering is a promising approach forwireless powering of miniature neural sensors required in BMI interfaces. We analyze the functionality of millimeter-size loop antennas in […]
Read moreWith the advent of smart portable devices and location-based applications, user’s mobility pattern is found to be highly dependent on varying locations. In this paper, we analyze asymptotic throughput-delay performance of mobile ad hoc networks (MANETs) under a location popularity based scenario, where users are more likely to visit popular locations. This work provides a […]
Read moreNext generation cellular network is expected to overcome the issues like demand for high data rates, better network coverage, energy, and spectrally efficient system. In this paper, femto based heterogeneous cellular network (HCN) with cognitive approach is considered to address these issues. This paper investigates two tier cognitive based HCN for overlay, underlay, and mixed […]

Design of rectangular microstrip patch antenna based on Artificial Neural Network algorithm
The Design of Rectangular Microstrip Patch Antenna using Artificial Neural Network (ANN) has been presented. This paper used Feed Forward Back Propagation Algorithm (FFBPN), Resilient Back-propagation (RPROP), Levenberg-Marquardt (LM) and Radial Basis functions (RBF) of ANN to obtain the resonant frequency of rectangular microstrip patch antenna. The model of ANN algorithm was developed and implemented […]
Read moreIn this paper, we present a maximum likelihood (ML) based time synchronization algorithm for Wireless Body Area Networks (WBAN). The proposed technique takes advantage of soft information retrieved from the soft demapper for the time delay estimation. This algorithm has a low complexity and is adapted to the frame structure specified by the IEEE 802.15.6 […]
Read moreVehicular Ad-Hoc Network (VANET) is an exponential growing technology in today’s modern computing era. Vehicle are peers of peer to peer network. All vehicles are having mobility. In this paper we have presented an evaluation of routing protocols AODV, DSDV and DSR on basis of test performance metrics like generated packets, received packets, dropped packets, […]
Read moreThis brief describes a built-in self-test (BIST) technique used to verify and tune the timing integrity of a clock distribution system implemented with injection-locked rotary traveling-wave oscillators (RTWOs). The die is fabricated in a 130-nm CMOS process and occupies 4.4 mm × 2.25 mm and is limited by the outer diameter of the RTWOs, leaving […]

The Application of SOM Network to Particle Tracking Velocimetry in a Wind-Blown Sand Flow
Wind-blown sand flow is the basic phenomena that have profound influences on the environment, and the experimental study on the velocity distribution of the sand particles is very important for the understanding of this phenomena. Among the various experimental techniques, particle tracking velocimetry (PTV for short) is one that attracts more and more attentions. In […]
