| Abstract: |
| A proposal for star topology satellite communication (SATCOM) network is designed based on tradeoff between network throughput and anti-jamming capability. The anti-jamming transmission waveform, network structure, and operational principle are introduced and user capacity and anti-jamming capability are theoretically computed. The computed result shows that the user capacity for one channel transponder is about 360, and 120~140 at direct sequence spread spectrum(DSSS) mode and frequency hopping(FH) mode respectively,and the proposal is of high anti-jamming capability. The networking proposal is valuable for engineering practice. |
