- Abstract
- A rapid growth of radio services leads to the deficiency of frequency resource, but the utilization of the radio service at M/W band is very low, relatively. Therefore, wideband characteristics at 8GHz band, is requested to solve the deficiency of frequency resources. The wideband characteristic such as the delay spread of multipath signals was measured with a channel sounder under LOS environment. And, the delay spread model was proposed from the measured results. The model was compared with ITU-R model and they were agreed well at similar conditions. But, it needs more measurements and analysis of some environments such as suburban areas and non-LOS conditions. After then, the delay spread model will be completed and it could be grasped a characteristics of M/W band according to radio environments.
