%% rssi(dBm) versus distance (log scale)
% We will plot the rssi versus the distance with the data before the passing of the train, and with the data after the passingof the train
% We will plot the rssi versus the distance. We separate the data
% before and after the passing of the train for run 3 and run 4 because
% all the antennas are poiting at the same direction
% we heuristically determine a starting point and a ending point for the linear fitting
