Abstract:
1. A method of performing channel simulation, in which method the channel simulation of a mobile radio system is performed digitally, the method comprising: transforming at least a section of a signal to be fed to simulation by convolution transformation from time space to transformation space; weighting the transformed signal by a channel impulse response that is transformed from the time space to transformation space; inverse-transforming the weighted signal to time space; dividing the channel impulse response into at least first and second sections wherein the channel impulse response comprises more elements than there are in the signal section to be fed to simulation; delaying the signal to be fed to simulation; and weighting each delayed signal section by the first section of the channel impulse response, and weighting the undelayed signal to be fed to simulation by the second section of the channel impulse response.
