摘要： The present disclosure describes the concept of operations and the medium access control protocols of a wireless communication system using code-division multiple access with interference avoidance (CDMA-IA) as its physical layer. The system can dynamically share a common band with other networks without a central radio resource controller. In one embodiment, the wireless communication system includes a plurality of radio nodes forming a wireless mesh network, wherein the pairs of radio nodes use, individually optimized, time division duplexing. At least one radio node includes a software-defined radio, a memory, and an electronic processor. The electronic processor is configured to control the software-defined radio to transmit a pilot signal and share various state information with the other nodes of the network. The shared information includes local spectrum occupancy and node connectivity sets. The pervasive sharing of spectrum occupancy among all nodes enables the usage of the shared band to be maximized.

摘要： Devices, methods, and systems for uplink synchronization in time division multiple access (TDMA) satellite network. In one embodiment, an earth-based satellite terminal is configured to communicate with a satellite hub through a satellite using the TDMA communication protocol. The earth-based satellite terminal is configured to determine its own location, a location of the satellite, estimate a distance between the location of the terminal and the location of the satellite, determine a Coarse Timing Advance based on the distance that is estimated, and transmit data to the satellite based on the Coarse Timing Advance and the TDMA communication protocol. The Coarse Timing Advance may allow uplink TDMA communication without a preamble transmission on a random access channel, the preamble transmission being required in many conventional systems.

摘要： Systems and methods for simultaneous multi-path TCP data flows over a plurality of transport paths, such as satellite and terrestrial networks. One system enables the plurality of paths to be used for increasing the end-to-end transport reliability or throughput of the network, depending on the prevailing reliabilities of the paths. One method includes determining, with a first electronic processor, a first reliability for a first network path configured to carry a first data stream, and a second reliability for a second network path configured to carry a second data stream. The method includes transmitting the first and second reliabilities to a second electronic processor. The method includes receiving a selected mode based on the first and second reliabilities, said mode indicating whether the plurality of paths are being used to enhance reliability or throughput. The method includes receiving the first and second data streams, and processing the first and second data streams based on the selected mode. The method includes determining the relative delays between the plurality of paths and equalizing the delays through buffering, which may be performed either at the transmitter, the receiver or both.

摘要： Systems and methods for exchanging data over a network are described. One method includes receiving, from a computing device via a physical network port, a request to forward network traffic, the request including a network domain identifier and a user identifier. The method includes retrieving, from a database storing user information, a user profile based on the user identifier. The method includes determining whether the traffic forwarding request is valid based on the user profile. The method includes, when the traffic forwarding request is valid, provisioning, on the network, an application service virtual circuit between a local virtual port of a communication interface coupled to the electronic processor and a peer port at a remote communication endpoint. The method includes forwarding the network traffic from the computing device to the remote communication end point via the application service virtual circuit.

The FDD wireless terminal is configured to selectively refrain from transmitting over the return link from at least one of the spaced-apart antennas of the FDD wireless terminal in response to differentials in forward link power that is received at the spaced-apart antennas of the FDD wireless terminal, that are caused, for example, by blocking appendages of a user of the wireless terminal. Related methods are also described.
