Hybrid Beamforming With Sub-arrayed MIMO Radar: Enabling Joint Sensing and Communication at mmWave Band [PDF]
, 2018 In this paper, we propose a beamforming design for dual-functional radar-communication (DFRC) systems at the millimeter wave (mmWave) band, where hybrid beamforming and sub-arrayed MIMO radar techniques are jointly exploited.

Kendali Formasi Multi-UAV menggunakan Line of Sight (LOS) Guidance Law
Setrum : Sistem Kendali-Tenaga-elektronika-telekomunikasi-komputer, 2017 Ketika suatu UAV (pesawat tanpa awak) sudah mencapai batas kemampuannya, maka diperlukan multi-UAV untuk menggantikan tugas yang dibebankan kepada UAV. Selama ini multi-UAV lebih dipilih dalam menjalankan tugas yang besar sehingga didapatkan tingkat efektivitas yang lebih tinggi disertai kemampuan bertahannya yang lebih bagus dibandingkan milik UAV ...

UWB Channel Modeling Improvement in Indoor Line-of-Sight (LOS) Environments
International Journal of Communications, Network and System Sciences, 2010 Channel measurement and modeling is an important issue when designing ultra wideband (UWB) communication systems. A Precise model of the channel response is inevitable for designing an ultra wideband telecommunication system. In this article signal propagation in indoor environment and LOS condition is evaluated and the appropriate model of this ...
