One of the key elements of radio resource management in mobile networks is MAC (Media Access Control) scheduling. The scheduling algorithms play a role in overall network performance and are not specified in the Long Term Evolution (LTE) standards. This paper describes how to assess the performance of a scheduler implementation by designing an adaptive […]
Read moreA 2.6 GHz cascode CMOS power amplifier with the derivative superposition (DS) method and the second harmonic control for LTE application is fabricated in TSMC 1P6M 0.18 μm standard CMOS process. The DS method uses two transistors connected in parallel and biased in low and high inversions to compensate for the gm3 and achieves the greater third-order intercept […]
Read moreThis paper proposes a novel interference-resistant receiver for wideband long-term evolution (LTE) system which employs orthogonal frequency division multiple access (OFDMA) for the downlink. In case the received spectrum is underutilized, compressed sensing (CS) enables us to operate at a sub-Nyquist sampling rate for lower device cost, higher data transmission rate and faster spectrum sensing […]
Read moreIn this letter, a wideband semisolid skin-equivalent phantom with dielectric properties close to human skin in the V and W band is proposed. The constituents of the phantom are deionized water, agar, and gelatin powder. The phantom has been fabricated and validated by an open ended waveguide method. Since it comprises of low-cost constituents and […]

Impulsive Multiconsensus of Second-Order Multiagent Networks Using Sampled Position Data
A multiconsensus problem of multiagent networks is solved in this paper, where multiconsensus refers to that the states of multiple agents in each subnetwork asymptotically converge to an individual consistent value when there exist information exchanges among subnetworks. A distributed impulsive protocol is proposed to achieve multiconsensus of second-order multiagent networks in terms of three […]
Read moreThe diversity provided by disjoint paths can increase the survivability of communication networks. This paper considers the allocation of network error correction flow on a network that consists of disjoint paths from the source node to the destination node. Specifically, we propose an algorithm of allocating the path-flows to support the given rate with minimum […]
Read moreIn mobile cloud computing systems, cloud computing has a significant impact on wireless networks. Cloud computing and wireless networks have traditionally been addressed separately in the literature. In this paper, we jointly study the operations of cloud computing and wireless networks in mobile computing environments, where the objective is to improve the end-to-end performances of […]
Read moreIn this paper, we study the capacity and delay scaling laws of cognitive radio networks (CRN) with static primary nodes (PNs) and mobile secondary nodes (SNs). The primary network consists of randomly distributed primary nodes of density $n$, which have a higher priority to access the spectrum. The secondary network consists of randomly distributed secondary nodes […]
Read moreMobile data traffic is expected to increase 11-fold between 2013 and 2018. A more dynamic and flexible network is needed to cope with the growing data volume. Software defined networking (SDN) enabled by, for example, the OpenFlow protocol is a potential solution to improve the flexibility and agility of the mobile data network by decoupling […]
Read moreNowadays, network management has become difficult because of tremendous increase on IP traffic demands. At this point, a flexible and dynamic control mechanism is needed that diminishes the complexity of physical topology. Software Defined Networking (SDN), is one of the proposed next generation technologies to overcome this problem. SDN paradigm provides a simple management strategy […]
