摘要： A system is provided for transmitting information through a speech codec (in-band) such as found in a wireless communication network. A modulator transforms the data into a spectrally noise-like signal based on the mapping of a shaped pulse to predetermined positions within a modulation frame, and the signal is efficiently encoded by a speech codec. A synchronization sequence provides modulation frame timing at the receiver and is detected based on analysis of a correlation peak pattern. A request/response protocol provides reliable transfer of data using message redundancy, retransmission, and/or robust modulation modes dependent on the communication channel conditions.

摘要： Techniques for transmitting and receiving data with hybrid automatic retransmission (HARQ) and network coding via block operation are disclosed. In one design, a transmitter transmits a first block of packets to multiple receivers and receives ACK/NAK feedback for the first block of packets from the receivers. The transmitter identifies candidate packets for network coding based on the ACK/NAK feedback. A pool of candidate packets changes over time as more ACK/NAK feedback for transmitted packets is received from the receivers. The transmitter generates at least one network-coded packet based on the candidate packets. Each network-coded packet may be generated by channel coding each of at least two packets and combining the at least two packets after channel coding. The transmitter transmits another block of packets to the receivers. This block includes the at least one network-coded packet and may also include pending packets and/or new packets.

摘要： Techniques for processing and forwarding transmissions by a relay are disclosed. In one aspect, an orthogonal distributed space-time frequency code (DSTFC) scheme that supports full-duplex relay operation and mitigates self-interference is disclosed. With the orthogonal DSTFC scheme, a source node transmits a same modulation symbol on two subcarriers in one symbol period. The relay obtains two received symbols from the two subcarriers and generates two output symbols based on these received symbols such that the output symbols and the modulation symbol are orthogonal at the relay and a destination node. In another aspect, a distributed Alamouti scheme is disclosed in which the source node transmits two modulation symbols on two subcarriers in each of two consecutive symbol periods. The relay obtains two received symbols from the two subcarriers in one symbol period and generates two output symbols based on the received symbols and in accordance with an Alamouti code.

摘要： A coax line terminal coupled to a plurality of coax network units by a coax plant uses time-division duplexing to communicate with the coax network units. In the coax line terminal, a control signal is repeatedly asserted and de-asserted. When the control signal is de-asserted, data are transmitted from the coax line terminal to the plurality of coax network units on a specified frequency band. When the control signal is asserted, transmission of the data ceases and data are received from respective coax network units on the specified frequency band.
