    Towards 6G: Spectrally efficient joint radar and communication with radio frequency selection, interference and hardware impairments (invited paper) by Aryan Kaushik, Evangelos Vlachos, John Thompson, Maziar Nekovee, Fraser Coutts

    Published 2022-09-01
    “…Abstract The joint radar‐communication (JRC) system is envisioned as an emerging sixth generation (6G) technology to tackle spectral congestion and hardware limitations by jointly implementing the communication and radar sensing on the same hardware platform and using the common radio frequency (RF) resources. Joint radar‐communication systems with a multi‐antenna setup leads to higher degrees of freedom, and hybrid beamforming can be exploited to achieve lower hardware complexity than conventional fully digital systems. …”

    Combining Individual‐Based Radio‐Tracking With Whole‐Genome Sequencing Data Reveals Candidate for Genetic Basis of Partial Migration in a Songbird by Matthias H. Weissensteiner, Kira Delmore, Valentina Peona, Juan Sebastian Lugo Ramos, Gregoire Arnaud, Julio Blas, Bruno Faivre, Ivan Pokrovsky, Martin Wikelski, Jesko Partecke, Miriam Liedvogel

    Published 2025-01-01
    “…We generated whole‐genome sequencing data for 60 individuals, each of which was phenotyped for migratory behavior using radio‐telemetry tracking. These individuals were sampled across the species' distribution range, including resident populations (Spain and France), obligate migrants (Russia), and a partial migratory population with equal numbers of migratory and resident individuals in Germany. …”
