摘要： Techniques for framing data in various data transmission contexts are described. A data framing technique may include a transmitter sending a data stream including repeating bits in alternating forward and reverse order. A receiver of the data stream may fold the data stream, and correlate portions of the folded data stream for purposes of validating the data stream and/or identifying an ID in the data stream. In at least some instances, once the receiver validates the data stream, the receiver may accept payload accompanying the data stream.

摘要： This application discloses a sequence generating method and apparatus, and relates to the field of communications technologies, to resolve a problem that a PAPR of a DMRS symbol is higher than that of a data symbol. An initialization factor of a first sequence is obtained, where the initialization factor is associated with a first parameter, and the first sequence is generated based on the initialization factor. In addition, the first parameter is a port number, or the first parameter is a code division multiplexing CDM group identity.

摘要： Infrastructure electronics equipment incorporates infrastructure Local-Site Transports (LSTs). LSTs convey payload sampled signals over imperfect electromagnetic (EM) pathways whose physical properties are usually unknown when the equipment (e.g., Cameras, Displays, Set-Top Boxes) is manufactured. Prior LSTs hedge against EM pathway degradation in several ways: requiring high-quality cables (e.g., HDMI); restricting transmission distance, (e.g., HDMI); and/or reducing quality, via compression, to extend transmission distance somewhat (e.g., Ethernet). The subject of this disclosure is an infrastructure LST for sampled signals that causes the physical errors inevitably arising from propagation of sensory payloads over imperfect EM pathways to manifest in a perceptually benign manner, leveraging legacy infrastructure and reducing costs to achieve a favorable ratio of fidelity to transmission distance.

摘要： Example communication systems and methods are described. In one implementation, a method receives a first chaotic sequence of a first temporal length, and a second chaotic sequence of a second temporal length. The method also receives a data symbol for communication to a destination. Based on the data symbol, the second chaotic sequence is temporally shifted and combined with the first chaotic sequence to generate a composite chaotic sequence. The first chaotic sequence functions as a reference chaotic sequence while the second chaotic sequence functions as a data-carrying auxiliary chaotic sequence.

摘要： Presented is a generator of binary code shift key (CSK) codes pre-saved to memory usable for time synchronous CSK code retrievals with extraction capability for 1 of 16 orthogonal CSK symbol codes under control of a supported communications system. The CSK code generator pre-defines a 1332 root prime number sequence containing 6 unique prime numbers including 221-7s, 222-11s, 221-13s, 223-17s, 222-19s, and 223-23s that receive multiple index shuffles of 1332 indexes. Pairs of 1332 shuffled indexes of prime sequences are then merged and formatted into 100 tier0 100 hex character format codes. Two levels of XORs of hex character format code pairs generate CSK codes that are collected into 10000 code files that are saved to memory. Time-synchronous CSK code retrieval is followed by 1 of 16 CSK orthogonal symbol codes extraction based on new half-byte data values under flow control of the supported communications system.

摘要： The present application discloses a method in which a base station transmits a reference signal sequence in a wireless communication system. In detail, the method comprises the steps of: generating a pseudo-random sequence using a first m-sequence and a second m-sequence; generating the reference signal sequence using the pseudo-random sequence; and transmitting the reference signal to a mobile station via antenna ports different from one another. The second m-sequence has an initial value containing parameters for discriminating reference signal sequences among users.

摘要： Fully connected uplink and downlink fully connected relay network systems using pseudo-noise spreading and despreading sequences subjected to maximizing the signal-to-interference-plus-noise ratio. The relay network systems comprise one or more transmitting units, relays, and receiving units connected via a communication network. The transmitting units, relays, and receiving units each may include a computer for performing the methods and steps described herein and transceivers for transmitting and/or receiving signals. The computer encodes and/or decodes communication signals via optimum adaptive PN sequences found by employing Cholesky decompositions and singular value decompositions (SVD). The PN sequences employ channel state information (CSI) to more effectively and more securely computing the optimal sequences.
