Abstract: Characters of spacial channel influence transmitting electromagnetic wave. Many measures are used for reducing these impacts andimproving performance of communication. Devices of wireless communication produce additional outcome which is harmful to system. The paperanalyses all kinds of factors which debase systemic performance and provides solution to the problem referring to 3G system.
