| Abstract(in English) | This paper describes characteristics of direct and scattered waves which are extracted from the measurement channel data which are obtained by using 3.35 GHz vector channel sounder in indoor environments. Moreover, we propose the basic concepts of spatio - temporal channel model based on the above mentioned measurement data. For the scattered waves, ray number are assigned to each rays in order of received levels and relation between the ray number and the characteristics of each rays such as received levels delay time and azimuth angle of arrival (AOA). We clarify received level of each rays decay according to the ray number linearly and distributions of the rays are log normal. Further, rays whose received levels are relatively large arrive from the direction of transmission antenna mainly and distribution of azimuth AOA of rays becomes uniform when the received levels of rays decrease. |
