    I have a question about the Set_LOS_factor in channel.cpp, with the argumment it needs. A Rice distribution is characterized by the K factor, which is the cocient between the direct component and the diffused, so my question is if this is the parameter which needs the function, or other, becuase in the channel models, for example in COST259_RAx, the paramter passed to the function is sqrt(0.91/0.41) and I don't understand.
    Thanks in advance!

      Hi Cesar.

      You are right. There are two parameters in set_LOS() function: relative_power and relative_doppler. The relative_power is K factor in linear scale, i.e. relative_power = inv_dB(K_factor_dB). The relative_doppler is a scaling factor related to the maximum Doppler frequency for LOS component (from 0 to 1).
