    摘要： Systems, methods, computer program products, and devices provide for computing an eigensystem from a first data set; computing updated eigenvalues that approximate an eigensystem of at least a second data set based on the eigensystem of the first data set; and evaluating a plurality of features in each of the first and at least second data sets using a cost function. The cost function uses fewer than the total number of eigenvalues and can include a condition number. The cost function can perform a coarse approximation of the eigenvalues to de-select at least one of the data sets. This can be useful for learning and/or online processing in an artificial neural network.

    摘要： A transmitter in a wireless communication network encodes data bits of a first layer to produce a set of coded symbols; spreads the coded symbols using discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-s-OFDM); and modulates the spread symbols onto a set of OFDM subcarrier frequencies to produce a discrete-time OFDM signal. Spreading is configured to map the coded symbols to a first sparse DFT-s-OFDM code space in a DFT-s-OFDM symbol, wherein the first sparse DFT-s-OFDM code space is different from a second sparse DFT-s-OFDM code space in the DFT-s-OFDM symbol, the second sparse DFT-s-OFDM code space being employed by a second layer.

    摘要： Disclosed techniques for improving computational efficiency can be applied to synthesis and analysis in digital signal processing. A base discrete-time Orthogonal Frequency Division Multiplexing (OFDM) signal is generated by performing at least one linear transform, including an inverse discrete Fourier transform (IDFT), on a first matrix of data symbols. A sparse data matrix is provided as an update to the first matrix of data symbols. The at least one linear transform is performed on the sparse data matrix to generate an update discrete-time OFDM signal. The update discrete-time OFDM signal and the base discrete-time OFDM signal are summed to produce an updated discrete-time OFDM signal.

    摘要： A wireless user equipment (UE) device is configured to communicate with another UE via device-to-device (D2D) communications. The UE transmits a communication to the other UE, wherein the communication indicates scheduling of a shared spectrum resource. The shared spectrum resource is shared by a first network management operator (NMO) and a second NMO, wherein both the UE and the other UE are associated with the first NMO. The first NMO employs a first set of spatial channels in the shared spectrum resource, and a second set of spatial channels in the shared spectrum resource is made available for use by the second NMO, the second set being different from the first set. The UE communicates with the other UE over the first set of spatial channels.

    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 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 radio devices identified as a threat and may coordinate other UAVs to conduct such mitigations.

    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.
