Abstract :
On the basis of considering downlink power flux density limit and frequency reuse in several systems simultaneously, the capacity of a CDMA mobile satellite communication system adopting voice activity, polarization isolation, and frequency reuse in adjacent beams is considered. Orthogonal codes are analyzed and calculated in this paper, and compared with those of TDMA and FDMA systems
