  • Large-Scale Fading Based Power Allocation for Device-to-Device Underlay Cellular Communication
    2015 IEEE 81st Vehicular Technology Conference (VTC Spring), 2015
    Co-Authors: Qiang He, Yunzhou Li, Jing Wang
    Abstract:

    Device-to-Device (D2D) underlay Cellular Communication has been recently considered as a popular paradigm to enhance system performance. In this paper, we study a power-allocation problem to maximize the system sum-rate while giving priority to Cellular users (CUs), assuming that only large- scale fading information is known at the base station. Specifically, we give priority to CUs by introducing outage probability constraints. Further, we adopt the geometric programming technique to solve the optimal power-allocation problem. Numerical results show that the proposed outage- constrained power allocation scheme not only provides more reliable Cellular Communication but also improves the system sum-rate performance.

  • mmwave cmos power amplifiers for 5g Cellular Communication
    IEEE Communications Magazine, 2019
    Co-Authors: Sherif Shakib, Jeremy Dunworth, Vladimir Aparin, Kamran Entesari
    Abstract:

    This article covers the basics of millimeter-wave PA design in CMOS technology for integrated phased arrays, targeting the upcoming 5G new radio (NR) Cellular Communication standard. Key PA figures of merit, as well as application of beam-forming phased arrays to combine power over-the-air, are briefly reviewed. Then, starting from practical handset form factor constraints and system-level drivers, CMOS-specific technological and design-related challenges are conceptually illustrated using a simple single-transistor PA. A survey of the state-ofthe- art is presented to give examples of the challenges and illustrate the PA techniques used to tackle them in linear 28-GHz CMOS PAs for 5G NR.

  • ICUFN - System level simulation for 5G Cellular Communication systems
    2017 Ninth International Conference on Ubiquitous and Future Networks (ICUFN), 2017
    Co-Authors: Seungyeob Chae, Chung G. Kang
    Abstract:

    In 5G Cellular Communication systems, a new type of simulation methodology may be required due to the emergence of new services and applications, new environments and requirements, new performance indicators, and increased need for accurate end-to-end performance measurements of systems including wired and wireless sections. In this paper, we address the characteristics of 5G simulations compared with 4G simulations especially focusing on system level simulation. Considering the characteristics of 5G simulations, the requirements for 5G simulators can be derived. In order to fulfill the requirements, a system level simulator is currently being developed and some selected features of the simulator are presented.
