摘要： A system incorporates TH-IR and TR-IR transceivers in the same wireless network. A transmitter modulates a sequence of bits in a wireless communications network by generating a reference waveform and a data waveform of a waveform pair for each current bit. The phase of the reference waveform depends on a previous modulated bit, and a difference in phase between the reference waveform and the data waveform pair depend on the current bit.

摘要： A method communicates data between terminals in heterogeneous communications network. A coordinator broadcasts periodically a first beacon in a first signal format. The first beacon defines a start of a contention period and a start of a contention free period. The coordinator also broadcasts a second beacon in a second signal format during the contention free period. The second beacon also defines the start of the contention period and the start of the contention free period.

摘要： A method and system communicates ultra wide bandwidth signals using orthogonal frequency division multiplexing modulation. QPSK input symbols are frequency interleaved. The frequency interleaved symbols are spread over a plurality of tones, and the tones are modulated for transmission over an ultra wide bandwidth channel. When the tones are received, the received tones can be de-spreaded to recover the input symbols.

摘要： A method and system communicates ultra wide bandwidth signals using orthogonal frequency division multiplexing modulation. Tones are received over an ultra wide bandwidth channel. The tones were generated from a single frequency interleaved input symbol subjected to spreading and modulation. The received tones are de-spreaded, and frequency de-interleaving is applied to the de-spreaded tones to recover the single input symbol.

摘要： A method and system use capacity-approaching rateless code to communicate multimedia data even with very short codewords, such as 64 bits or less, via erasure and noise channels. The method provides a way to design the edge degree distribution of rateless codes for any arbitrary channel. Based on an equivalent metric of decoding behavior in any channels, the degree distribution of a rateless code such as Luby-transform codes and raptor codes is optimized based on in-process status of decoding. A regularized least-squares optimization is used to avoid erroneous decoding. Multiple feedbacks can further improve the performance.

摘要： Packets are transmitted by a server to mobile nodes in a coverage area of a wireless network using a coverage and reliability map, which indicates qualities and reliabilities of links between the server and the nodes. When a new packet is received in the server, the server transmits the packet if a current load of the packets including the new packet is less than a peak load constraint. Otherwise, the new packet is delayed for one time slot.

摘要： A wireless mobile communication network allows mobile, nodes, such as cellular telephone, and other types of mobile transceivers, to communicate with a fixed base station and directly with one another. This mobile to mobile communication capability is exploited through the formation of a local link where nodes with excess processing and bandwidth capacity forward messages at the request of the base station. The formation of the local link is adaptive and does not require a central controller. The wireless mobile network includes a base station and mobile nodes. Nodes are configured as a major nodes when they communicate information directly with the base station via a network link. Nodes are configured as minor nodes when they communicate the information indirectly with the base station via a direct local link with one of the major nodes to form a locally linked mobile network within the wireless mobile communications network. Each mobile node includes a header detector, coupled to a receiver and a decoder of the node to detect a header in a frame used to communicate the information, and a message processor, coupled to the header detector and a transmitter, to route the frame to the minor node.
