摘要：
The CDMA (Code Division Multiple Access) satellite communications system which adopts multi-beam onboard transparent switch is reported less. Capacity analysis in this system is regarded as a new research field. In this paper, taking bandwidth-constraint and onboard power-constraint into comprehensive consideration, system capacity computation method is proposed. The factors which have influence on system capacity are deeply studied. Through particular system capacity analysis, the simulation results show the quantified values of influence on system capacity for various factors. The measures to improve system capacity are pointed out at last.
