<P>PROBLEM TO BE SOLVED: To obtain a fading simulator for simulating, in higher accuracy, the influence of Doppler shift in the receiving signal. <P>SOLUTION: The fading simulator 206 is provided with a noise generating means 322 for outputting Gauss noise signal, a low-pass filter means 324 connected with the noise generating means, a memory means 340 for storing amplitude data for the predetermined period for each of a plurality of predetermined frequencies, and a synthesizing means 212 for synthesizing the signal from the low-pass filter means and the signal extracted from the memory means and then outputting a fading signal. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
