WebTask: Select any open dataset relating to an urban or spatial system of your choice and conduct an advanced analysis of the dataset. A complete data analysis process should be undertaken – this will include data validation and cleaning, a data pre-processing phase (e.g. text, image, clustering analysis), and comprehensive analysis (including ... WebIn telecommunications, direct-sequence spread spectrum ( DSSS) is a spread-spectrum modulation technique primarily used to reduce overall signal interference. The direct-sequence modulation makes the transmitted signal wider in bandwidth than the information bandwidth. After the despreading or removal of the direct-sequence modulation in the ...
Web13 Sep 2024 · In mobile underwater acoustic (UWA) communications, the Doppler effect causes severe signal distortion, which leads to carrier frequency shift and compresses/broadens the signal length. This situation has a more severe impact on communication performance in the case of low signal-to-noise ratio and variable-speed … Web7 Apr 2024 · Most importantly, the DSSs should provide an intuitive and effective graphical interface to permit result interpretability for human supervision and understanding [17,18]. To this end, Geographical Information Systems (GISs) are fundamental tools for the management, analysis, editing, and visualization of geospatial data [19,20].
