Many antennas are highly resonant and only operate over a few percent of the center frequency. These narrow bandwidth antennas may be entirely satisfactory or even desirable for single-frequency or narrow band applications. Wider bandwidths may be required in applications such as Vehicle Communications (VC), where it may be necessary to transmit high bandwidth or latency dependent data. In this application,...
With the development of wireless communication technologies, the mobile terminal can be installed with more than one wireless interfaces to support its flexible roaming and vertical handover between heterogeneous access networks. Traditionally, the ongoing session has to be re-established when the multi-interface terminal hands over vertically while maintaining the Delay Tolerant Networking (DTN)...
This paper investigates the bit error probability of a wavelet-time diversity transmission system, which exploits the orthogonality properties between wavelet matrix rows to spread the information of QPSK symbols before transmission. Numerical results of performance comparisons show that the proposed theoretical analysis very accurately matches with the Monte Carlo simulation results. Besides, analytical...
Smartphones and other devices connected to a mobile network typically create billions of measurement samples every day. Those measurements are currently used for instantaneous resource allocation and link adaptation. There is much room for using the measurements also for network optimization with big data analytics. The measurements give valuable insight into the service quality experienced by devices...
This paper studies the problem of using path constrained mobile sinks (MSs) to collect data in Wireless Sensor Networks (WSNs). Accounting the feature of nonuniform node distribution, the proposed protocol aims at balancing the energy consumption, including energy expenditure to transmit data packet and network overhead, to make the network operate as long as possible with all nodes alive. We propose...
A distributed target search and predictive approach that uses wireless sensor network topology map is presented in this paper. The decision-making and information gathering is distributed, and the target prediction is based on the weighted least square method. The knowledge of target location and moving direction is obtained by time sets recorded by each sensor node. Time set is a collection of time...
Solving systems of linear equations is important both in classical and quantum computing. Harrow- Hassidim- Lloyd algorithm (HHL algorithm), a quantum algorithm for solving systems of linear equations, has achieved exponentially improved performance compared with corresponding classical algorithm. We will show in this article that the HHL algorithm is actually a duality quantum algorithm with non-...
The standardization for the fifth generation (5G) of mobile and wireless networks is at its early phase and has recently completed the first study item in Release 14. Nevertheless, there is a consensus that 5G will address the diverse service requirements of high-variety use cases. The network shall cope with such variation effectively and cost-efficiently even though the requirements can change over...
Offloading traffic from the macro cells (MCs) with limited frequency resources to the high frequency small cells (SCs) improves the spectral efficiency and the energy efficiency in the inter-frequency heterogeneous networks (HetNets). Inter-frequency measurement (IFM) is an essential process prior to offloading terminals and their traffic to the SCs, and has a great impact on the utilization of the...
A highly efficient leaky-wave antenna (LWA) array is presented in this paper. The proposed LWA array covers 28-GHz millimeter-wave frequency band and can be useful for 5G terminals. The antenna has been designed to be integrated to a substrate of dimensions 120 mm × 70 mm and occupies a small area of 24.5 mm × 24.5 mm. A dielectric load is used to increase the antenna efficiency. The efficiency of...
