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