11GHz室内场景中具有人体遮挡的无线传播特性研究
Research on propagation characteristics of wireless channels with human body shadowing in 11 GHz indoor scenarios
摘要
Abstract
The characteristics of wireless channel are investigated in indoor scenarios at 11 GHz,with a specific focus on the influence of height differences between transmitting and receiving antennas,as well as human body obstruction on signal propagation.Based on measurement data,a path loss(PL)model with height difference and human body occlusion is proposed,a comparative analysis is conducted in office,corridor and large laboratory scenarios.The research indicates that the variation of PL with height differences conforms to a quadratic function distribution with-out human body occlusion.When the transmitter height is below the human height to the hip position,the PL caused by human body occlusion can be approximately described by a quadratic function relationship with their dis-tance from the transmitter.However,when the transmitter height exceeds that of human body,their relationship can be approximately described by a cubic function.The research results can lay the foundation for the design of in-door body area network communication systems.关键词
