A radio wave propagation estimation device (4) comprises an extraction unit (14) that extracts, from map information acquired by a map information acquisition unit (11), estimation-use map information which is used for estimating the propagation characteristics of radio waves, such extraction carried...

# Size of a cell of the radio map mp_cell_size=np.array([1.,1.]), # Number of paths to compute the radio map num_samples=int(1e7), # Maximum number of interactions max_depth=10) # Ray trace the radio maps # pm: Path loss map ...
“double-click” station from WSJT-X, harvest the Grid Square, and send it to HamClock. So now when you click on a station calling CQ on FT-8, the HamClock map will then set the DX on the display and you will see the path, range and bearing, etc. That’s both cool and ...
[30], a rough execution flow can be obtained: the first step of preprocessing includes the generation of the convolution coefficient matrix and the address map lookup. The second step multiplies the sampled data by the corresponding convolution kernel according to thelookup tableand then adds them...
