| Abstract: | It is appeared that wide band code divison multiple access has become the mainstream in air interface solution of third generation mobile system and wide band satellite mobile communication is expected to develop more rapidly. In this paper, based on a brief analysis of transmission characteristics of satellite mobile communication channel, we present and simulate a channel model of wide band satellite mobile communication. We also set up a transmission and receiving system of K user wide band DS CDMA and study the basis code error property on down link of a satellite mobile communication in the environment of urban, suburban and rural areas. |
