In this website, we release our codes for generating realistic wireless channels in 2D.
The wireless channel simulator can generate simulated 2D wireless channels
(received power over 2D in transmission from a fixed transmitter) by properly modeling the three underlying dynamics of
a wireless channel, which are path loss, shadowing and multipath fading. The code is written in Matlab. The figure below shows a
sample simulated wirelss channel with the transmitter at [0, 0].
If you have any questions or comments regarding these codes, please contact Herbert Cai.
Code Download
The Matlab codes can be downloaded from the link below.
You may want to start with the demo script "test_channel.m". More details can be found
in the Documentation, which includes description of the variables used.
Mathematical details on how the wireless channel is simulated can be found in the following paper (Section 6).
