Modelling diffuse components in geometry-based radio channel models is computationally very complex. It usually requires to add a large number ofcomplex exponentials, which is very time consuming. To overcome thiscomplexity constraint, we propose to use the simulation method from Kaltenberger et al. [1]. With this approach, the simulation time becomes independent of the number of multipath components in the channel. We demonstrate the low-complexity approach by modelling the diffuse componentsof the vehicular radio channel. Our new implementation reduces simulation time by a factor of 30, while keeping the maximum error more than 30 dB below the power of the simulated channels.
