| 摘 要： | 近年来PCMA等卫星通信新技术的应用对卫星通信信号的截获提出了更高的要求,通过分析PCMA卫星通信系统的工作原理,借鉴多用户检测技术中串行干扰抵消的基本思想,提出一种针对非对称PCMA信号的截获方法,并进行了性能仿真。仿真结果表明,在没有任何先验信息的情况下,可以实现对非对称PCMA信号中双方信号的截获和解调。

| Abstract: | In these years,more and more strict challenges are presented to satellite communication signal interception,for applications of new satellite communication technology such as PCMA,and so on.After analysing the principle of PCMA systems and the use of theory of Serial Interference Cancellation(SIC) in Multi-user Detection technology(MUD) for reference,a method of signal interception in asymmetric PCMA is proposed and simulated.The simulation results show that signal interception and demodulation is implemented in the asymmetric PCMA systems without prior information. |
