Design of Wavelet‐Encoded Symbol Constellations for Cyclostationary Spectrum Sensing

Wireless Communications and Mobile Computing, Volume 2020, Issue 1, 2020., 2020
In mobile communication systems, the signals propagate through multipath over time‐varying channels, which are subject to distortion caused by fading and Doppler shifts. In order to minimize such distortions, coding techniques and transmission diversity can be employed, e.g., wavelet coding. In this work, the wavelet coding is investigated in scenarios

Evaluating CRoS-NDN: a comparative performance analysis of a controller-based routing scheme for named-data networking

Journal of Internet Services and Applications, 2019
The huge amount of content names available in Named-Data Networking (NDN) challenges both the required routing table size and the techniques for locating and forwarding information. Content copies and content mobility exacerbate the scalability challenge

Evaluation of Pigeon Pea Lines for Biological Soil Decompaction

International Journal of Agronomy, Volume 2009, Issue 1, 2009., 2009
Soil decompaction is generally achieved through mechanical cultivation practices; however biological processes can significantly add to this process through root growth, development, and later senescence. This study was carried out in Piracicaba, SP, Brazil and had the purpose of selecting, among forty one pure pigeon pea lines, the most efficient ...
