摘要
为了能够有效提高无线信道在频谱方面的利用率,可以采用多种方法,如对信源进行编码、使用多载波技术、使用自适应编码调制技术(ACM技术)等。因此,将针对ACM技术进行相关介绍。自适应编码调制技术进行IP网互联方案的提出,是为了更好地增加卫星通信在利用IP进行传输时需要的电路宽带。通过比较多种技术发现,ACM技术在卫星通信IP网互联中具有应用的可行性。
In order to effectively improve the frequency spectrum utilization of wireless channels,there are many methods that can be adopted,such as coding the source,using multi-carrier technology,using adaptive coding modulation technology(ACM technology),etc.,it will introduce the ACM technology. The scheme of IP network interconnection based on adaptive coding modulation technology is proposed in order to increase the circuit bandwidth for satellite communication when using IP for transmission. By comparing various technologies,it is concluded that ACM technology is feasible to be applied in satellite communication IP network interconnection.
