摘要： This invention is a multiple access communication technique by which a multitude of transmitters communicate with receivers using direct sequence spread spectrum signaling. The direct sequence codes are reused by a large number of simultaneous transmitters, so the system is named Code Reuse Multiple Access ("CRMA"). This reuse method requires only a small number of codes relative to the number of simultaneous transmitters, and can use as few as one code for all the users. The direct sequence codes are not required to have special properties such as maximal length. The lengths of the spreading codes employed are not necessarily related to the bit or symbol interval. CRMA can be implemented on a Paired Carrier Multiple Access ("PCMA") system with or without a novel receiver structure which is also described. In an environment having virtual channels, a clock is derived from the received signal in the uplink by sampling the signal to detect symbol edges.
摘要翻译：本发明是一种多址通信技术，通过该技术，多个发射机使用直接序列扩频信令与接收机进行通信。直接序列码被大量同时发射机重复使用，因此该系统被命名为码重用多址（“CRMA”）。这种重复使用方法只需要少量的代码，相对于同时发射机的数量，并且可以为所有用户使用少至一个代码。直接序列码不需要具有诸如最大长度之类的特殊属性。所使用的扩展码的长度不一定与比特或符号间隔有关。 CRMA可以在具有或不具有新颖接收机结构的配对载波多路访问（“PCMA”）系统上实现，其也被描述。在具有虚拟信道的环境中，通过对信号进行采样以检测符号边缘，从上行链路中的接收信号中导出时钟。

摘要： One or more satellites may generate multiple beams. The beams may facilitate communication over multiple communication frequency bands including a relatively high capacity frequency band and a relatively fade-resilient frequency band. The beams may overlap. User terminals and/or gateways in a beam intersection may select from among the multiple communication frequency bands to communication with the satellite(s). Responsive to detection of rain fade, some of the user terminals and/or gateways may be instructed to use the relatively fade-resilient frequency band. The multiple communication frequency bands may be assigned to the user terminals and/or gateways so as to maximize total system capacity.

摘要： A method for providing content from a first node to a second node using a satellite communications system includes receiving side information at a gateway in the satellite communications system. The side information may be transmitted from a subscriber terminal to the gateway via a first communication path that includes a satellite link. The method also includes determining at the gateway that the side information is associated with first content available at the first node, and determining at the gateway that second content is available from a source other than the first node. The method also includes generating output content using the second content and the side information. The output content may be substantially the same as the first content. The method also includes providing the output content to the second node via a second communication path that does not include the satellite link.
