FADING CHANNEL MODELING EQUIPMENT OF COMMUNICATION SYSTEM AND CHANNEL MODELING METHOD THEREOF

摘要

A fading channel modeling device of a communication system and a channel modeling method thereof are provided to reduce a calculation quantity for performing a simulation of the communication system by interpolating a channel gain when beginning the simulation after calculating the channel gain before the simulation. A random noise passes through a fading filter and a complex channel gain of a frequency domain is produced(S10). The complex channel gain adding the fading effect is produced by filtering the random noise in the fading filter according to a fading factor(S20). The complex channel gain of the frequency domain is inverse-discrete-Fourier-transformed and the complex channel gain of the outputted time domain is stored(S30). The complex channel gain of the stored time domain is interpolated according to the interpolation factor and is provided to the complex channel gain for the simulation(S40).
