We analyze Coordinated Multi-Point (CoMP) transmission and reception over heterogeneous wireless networks (HetNets). Our focus is on the design of a practical algorithm for joint resource allocation (joint scheduling) in each HetNet cluster. We present one such algorithm together with its detailed analysis and evaluation under two different approaches for obtaining and utilizing channel feedback […]
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 […]

A Predictive Resource Allocation Algorithm in the LTE Uplink for Event Based M2M Applications
Some M2M applications such as event monitoring involve a group of devices in a vicinity that act in a co-ordinated manner. An LTE network can exploit the correlated traffic characteristics of such devices by proactively assigning resources to devices based upon the activity of neighboring devices in the same group. This can reduce latency compared to waiting […]
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 […]
Read moreNetwork-on-chip (NoC) has emerged as a vital factor that determines the performance and power consumption of many-core systems. This paper proposes a hybrid scheme for NoCs, which aims at obtaining low latency and low power consumption. In the presented hybrid scheme, a novel switching mechanism, called virtual circuit switching, is proposed to intermingle with circuit […]
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 […]

Minimization of CSI Feedback Dimension for Interference Alignment in MIMO Interference Multicast Networks
It is well-known that interference alignment (IA) can achieve substantial theoretical gains in multiple-input multiple-output (MIMO) networks. However, the conventional works usually assume the full channel state information (CSI) is available at the transmitter side, which would create a overwhelming CSI feedback overhead for practical frequency-division duplexing (FDD) wireless systems. To implement IA in practice, […]
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 moreSoftware-defined deployments are growing into data center and enterprise network infrastructures. The typical promises of software-defined networks (SDN) are improved time for market, decreased risk and operational costs for services, flexibility and unified management. However, little is known and shared about how to actually manage an SDN network, especially in localising underperforming network paths (what […]
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 […]
