45GHz propagation channel modeling for an indoor conference scenario

Propagation channel model is crucial for the design of high-frequency communication systems. Measurement-based stochastic modeling approach which was commonly adopted in low frequencies is no more efficient or flexible due to the limitation of antenna gain and sounding efficiency. In this contribution, we propose a hybrid method which utilize both the measurements and ray-based deterministic simulations to study the channel characteristics in specified indoor environments. First, the ray-tracing tool is evaluated by using a small amount of measured data. And then we adopt the validated tool to generate massive samples of channel impulse responses. Fianlly, statistical models are constructed based on the proposed approach. The results show good compatibility with the recommended model suggested by METIS. Furthermore, the importance of diffuse scattering at high-frequency is also investigated.
