Corresponding with the path to receive power as well as the path delay difference between the simulation parameters of 2, channel sharp decline affects only the magnitude of the transmitted signal, does not affect the instantaneous phase. 3, in the symbol intervals multipath component of the decay rate is constant, and has nothing to do with the next interval.
