Summary:
Nowadays with the frequent occurrence of natural disasters, there is a great demand for accurate and fast novel localization technique for rescue. Thanks for the advancements of modern wireless communication technology, lots of people own a mobile phone today, and the most important thing is that the phone is often the only device people carried when such disasters happen, which can send a radio signal to prove their exist. Thus, we can take use of this fact to search and rescue the victims in disaster areas. This paper presents the characterizing radio channel modeling in collapse and measurement experiment, which is a key component for developing a novel passive radio localization system. The behavior of wireless channel can be regarded as a stochastic process, the channel is composed of many complex random obstacles, their influence on the mobile signal propagation is simulated and measured to set up a database, the statistical characteristics of channel can be determined through plenty of simulation and measurement data.
