Abstract :
This paper describes characteristics of direct and scattered waves that are extracted from measurement channel data obtained using a 3.35 GHz vector channel sounder in an indoor environment. Each ray of the scattered waves is designated a number in order of the received level. The relationship between the ray number and the characteristics of each ray such as the received level, delay time, and azimuth angle of arrival (AOA) are investigated.
