Method of radio channel simulation and channel simulator

摘要

The invention relates to a method of performing channel simulation and a channel simulator. The channel simulation is performed digitally. At least a section of a signal (206) to be fed to simulation is transformed by convolution transformation from time space to transformation space in tansformation means (200) of the channel simulator. In weighting means (202), the transformed signal (208) is weighted by a channel impulse response that is transformed from time space to transformation space. Finally, the resulting signal (210) is inverse-transformed in inverse-transformation means (204) to time space.
