THE CAPACITY CALCULATION FOR CDMA MOBILE SATELLITE COMMUNICATION SYSTEM
CDMA移动卫星通信系统容量的计算

On the basis of considering downlink power flux density limit, shadowing effect, frequency reuse in different systems and adjoining spots of same system, adopting voice activity and polarization isolation techniques, the capacity of CDMA mobile satellite communication system at different downlink power flux density limit mode, channel spread bandwidth and mobile user's quality factor of receiving system (G/T) are analysed and calculated, and compared with the ones of TDMA and FDMA. Finally, the conclusions are given.
