摘要： The present invention is a return link for a satellite communication system. The return link described herein is suitable for use in any type of communications network such as networks used for Internet access purposes. The return link in combination with a forward link forms a complete two way communication system via satellite. The return link comprises two separate communication schemes used in combination to implement the return link of the satellite system. The first communication scheme uses a random access method based on a non synchronous frequency hopping code division multiple access technique (NS/FH/CDMA). The second communication scheme uses a channel assignment method based on a frequency division multiple access (FDMA) technique. Data generated by a user is transmitted utilizing one of the two communication schemes in accordance with the content and amount of data generated. Messages requiring a relatively low transmission rate, such as short bursty messages, utilize the random access transmission method. On the other hand, messages requiring a higher transmission rate, such as video conferencing, utilize the channel assignment method.
摘要翻译：本发明是卫星通信系统的返回链路。本文描述的返回链路适用于任何类型的通信网络，例如用于因特网接入目的的网络。与前向链路相结合的返回链路通过卫星形成完整的双向通信系统。返回链路包括组合使用的两个单独的通信方案，以实现卫星系统的返回链路。第一通信方案使用基于非同步跳频码分多址技术（NS / FH / CDMA）的随机接入方法。第二通信方案使用基于频分多址（FDMA）技术的信道分配方法。根据生成的数据的内容和数量，利用两种通信方式之一来发送用户生成的数据。需要较低传输速率的消息，例如短突发消息，利用随机接入传输方法。另一方面，需要更高传输速率的消息，如视频会议，利用信道分配方式。
