    Planar Monopoles with Different Radiator Shapes for UWB Body-Centric Wireless Communications by Y. Y. Sun, S. W. Cheung, T. I. Yuk

    Published 2013-01-01
    “…A solid-body phantom mimicking human tissue is used for studies of these three monopoles for body-centric communications. Simulated and measured results of these monopoles on the phantom show that the horizontal elliptical monopole achieves the widest impedance bandwidths, highest average peak gain and efficiency, least path loss, best fidelity, and good radiation pattern, making it a good candidate for UWB body-centric wireless communications.…”

    Effective Lock Detectors Based on Costas Loop Output for SBPSK Mobile Communications by D. Ferramola, T. Casilli, S. Pradella, G. Giunta, D. Orlando

    Published 2025-01-01
    “…In this study, we address the problem of lock detection at the output of a Costas loop when robust modulations for bandwidth-constrained military communications are used. In this respect, we propose two novel detectors that share the important constant false alarm rate property with respect to the noise power. …”
