摘要
A modified random walk model for human motion is proposed to investigate characteristics of 60GHz indoor office propagation.Compared with the classic random walk model,the movement tendency in the walking process is taken into account in the modified model.Based on the proposed model,path gains of the propagation environment are simulated under a variety of settings by using a ray tracing method.Simulation results and analysis show that human motion is a major source of disturbance to the indoor office propagation and results in performance degradation in some areas.

Based on the proposed model, path gains of the propagation environment are simulated under a variety of settings by using a ray tracing method. Simulation results and analysis show that human motion is a major source of dis- turbance to the indoor office propagation and results in performance degradation in some areas.
