Character of Scattering Channel With Finite Wave Width

摘要

Different from previous analysis, the characteristics of received signals are investigated in wireless communication systems by considering finite wave width. The auto-variance function and corresponding spectrum are derived. It is found the channel characters are influenced by the beam width, it agrees with the existed model when the average wave width d is sufficient large, and the expected rate of level crossings (lcr) and average times under certain level (adf) have no relation with d.
