摘要： An OFDM transmitter spreads original data symbols with a complex-valued spreading matrix derived from a discrete Fourier transform. Spread data symbols are mapped to OFDM subcarriers. Spreading and mapping are configured to produce a transmitted spread-OFDM signal with a low peak-to-average power ratio (PAPR) and orthogonal code spaces. In MIMO systems, the complex-valued spreading matrix can comprise a MIMO precoding matrix, and the code spaces can comprise MIMO subspaces. In Cooperative-MIMO, a combination of low code-space cross correlation and low PAPR can be achieved.

摘要： A radio transmitter is provided with a data symbol vector produced from data bits mapped to a constellation set and a coding matrix generated from a secret key and an information signal. The data symbol vector is multiplied with the coding matrix to produce a coded signal comprising distorted data symbols. The radio transmitter generates a transmit signal from the precoded signal, which is transmitted to a receiver that separates the coding matrix from the data symbol vector and decodes the information signal from the coding matrix. Information from the data symbol vector can be communicated in a cellular network while information encoded in the coding matrix provides for communicating in a peer-to-peer network by using the cellular signal as a carrier for the peer-to-peer communications.

摘要： In a radio receiver, digital baseband signals are processed by a time-domain-to-frequency-domain converter to generate frequency-domain symbols. A blind-adaptive decoder processes the frequency-domain symbols to produce estimates of transmitted data symbols. Frequency-domain equalization may be performed prior to the blind-adaptive decoder performing at least one of blind-adaptive decoding and partially blind adaptive decoding based on information about the transmitted data symbols. The blind-adaptive decoder comprises a combiner that combines the frequency-domain symbols to produce the estimates of the transmitted data symbols.

摘要： A server selects edge-server sets to deliver data to client devices. To rapidly find an optimal or near-optimal edge-server set, the server constructs a trellis having a number of states at least equal to the number of edge servers to be included in an edge-server set. Each state comprises a plurality of nodes, wherein each node corresponds to one of the plurality of candidate edge servers. A trellis-exploration algorithm selects the edge-server set by providing interconnects between each node of a first state to each of a plurality of nodes in a next state, and for each node in a state, selecting a path corresponding to a best performance metric that connects to a node in a previous state. Each performance metric comprises network topology information, which can include channel measurements from candidate edge servers. When the edge-server set is selected, the server distributes content to the edge servers, which is then transmitted to the client devices.

摘要： An Unmanned Aerial Vehicle (UAV) comprises a situational awareness system coupled to at least one onboard sensor and senses the location of other UAVs. A cooperative Radio Access Network (RAN)-signal processor is configured to process RAN signals cooperatively with at least one other UAV to increase the rank of the RAN channel and produce RAN performance criteria. A flight controller provides autonomous navigation control of the UAV's flight based on the relative spatial locations of other UAVs and the RAN performance criteria, which operates within predetermined boundaries of navigation criteria. The UAV can employ mitigation tactics against one or more UEs identified as a threat and may coordinate other UAVs to conduct such mitigations.

摘要： An OFDM transmitter comprises a Discrete Fourier Transform (DFT) spreader configured to spread reference-signal symbols with Fourier coefficients to generate DFT-spread reference symbols, which are mapped to OFDM subcarriers. An OFDM modulator, such as an inverse-DFT, modulates the DFT-spread reference symbols onto the OFDM subcarriers to produce an OFDM transmission signal with low peak-to-average power.

摘要： A source node selects a plurality of transmitting nodes to cooperatively encode a set of original packets to transfer to a destination node. Encoding produces a plurality of coded packets and a corresponding code matrix of coefficients. The coded packets and the corresponding code matrix comprise a set of independent equations of independent variables in a system of linear equations, wherein the independent variables comprise the original packets. A destination node may select a set of receiving nodes to cooperatively receive the transmissions. The destination node collects the coded packets and code matrix from the receiving nodes, which provide a sufficient number of independent equations for decoding the original packets. Decoding comprises calculating a solution for the system of linear equations.

摘要： In a coordinated multipoint system, geographically distributed base transceiver stations employ overlapping coverage areas in a Radio Access Network (RAN) to serve multiple User Equipments (UEs). A fronthaul network communicatively couples the base transceiver stations to a central processor. The central processor comprises a cooperative multiple-input, multiple-output (MIMO) processor configured to select multiple antennas residing on multiple ones of the base transceiver stations to serve each of the UEs; compute baseband pre-coding weights for signals to be transmitted by the antennas, the baseband pre-coding weights computed from RAN channel state information between the antennas and the UEs; and coordinate transmissions of pre-coded signals from the antennas to exploit multipath in the RAN to coherently combine at each of the UEs. Since each UE can be provided with its own localized coherence zone, this enables the UEs to concurrently employ the same frequency spectrum.
