TLDR
A novel method for efficient computation of complex channel characteristics due to multipath effects in urban microcell environments by tracing continuous beams and by using parallelization techniques is presented.Abstract:
We present a novel method for efficient computation of complex channel characteristics due to multipath effects in urban microcell environments. Significant speedups are obtained compared to state-of-the-art ray-tracing algorithms by tracing continuous beams and by using parallelization techniques. We optimize simulation parameters using on-site measurements from real world networks.read more
