Abstract: The present development details a method and apparatus for performing channel emulation of doubly selective scenarios, where the simulation and emulation duration is arbitrarily long for a stationary or non-stationary channel, with non-separable dispersion which is achieved by combining the techniques of channel orthogonalization, decomposition of the correlation tensor in the Doppler domain into frequency-dependent correlation matrices, followed by a matrix factorization of each of the mentioned matrices and, finally, the use of the windowing method to generate arbitrarily long achievements which thereby allows the concatenation of channel realizations coming from the same or different NSSF, thus achieving reproduction of stationary or non-stationary channels, respectively.

Abstract: A dark fiber dense wavelength division multiplexing service path design microservice (ddSPDmS) can provide a scalable self-contained meta-data driven approach for a flexible implementation of a dark fiber dense wavelength division multiplexing (DWDM) service path design solution. The service plan design solution can be used as a standalone solution or integrated with a network management application. In order to manage a large volume of circuit designs, multiple microservices can accept application program interface (API) requests in a cloud environment. Permission can then be given to any application to use the API to make a call to the design and inventory. Additionally, metadata templates can be designed to support a node, a link, and/or a topology for the microservices.

Abstract: A novel and useful radar sensor incorporating detection, mitigation and avoidance of mutual interference from nearby automotive radars. The normally constant start frequency sequence for linear large bandwidth FMCW chirps is replaced by a sequence of lower bandwidth chirps with start frequencies spanning the wider bandwidth and randomly ordered in time to create a pseudo random chirp hopping sequence. The reflected wave signal received is reassembled using the known hop sequence. To mitigate interference, the signal received is used to estimate collisions with other radar signals. If detected, a constraint is applied to the randomization of the chirps. The chirp hopping sequence is altered so chirps do not interfere with the interfering radar's chirps. Offending chirps are re-randomized, dropped altogether or the starting frequency of another non-offending chirp is reused. Windowed blanking is used to zero the portion of the received chirp corrupted with the interfering radar's chirp signal.

Abstract: This disclosure provides systems, methods, and apparatuses for wireless communication that can be used to reduce the peak-to-average power ratio (PAPR) of data transmissions by increasing the degree of randomness with which data is scrambled for transmission over a wireless medium. In some implementations, a transmitting device may determine a set of scrambling initialization bits, and may generate a scrambling sequence based on the set of scrambling initialization bits and an 11th-order polynomial.

In some instances, the set of scrambling initialization bits consists of 11 bits, and may be included in a Service field of the PPDU.

Abstract: A system includes a host processor, which has a host memory and is coupled to store data in a non-volatile memory in accordance with a storage protocol. A network interface controller (NIC) receives data packets conveyed over a packet communication network from peer computers containing, in payloads of the data packets, data records that encode data in accordance with the storage protocol for storage in the non-volatile memory. The NIC processes the data records in the data packets that are received in order in each flow from a peer computer and extracts and writes the data to the host memory, and when a data packet arrives out of order, writes the data packet to the host memory without extracting the data and processes the data packets in the flow so as to recover context information for use in processing the data records in subsequent data packets in the flow.

Abstract: A method and system for limiting mobile device functionality when the mobile device is located in a pre-defined fixed geographic area. The mobile device may receive a local disabling signal from a disabling device, which, when detected by a Device Owner Application resident on the mobile device, limits the mobile device functionality. Alternatively, the system may use GPS based geofencing to determine that the mobile device is in a predefined geographic area, and then transmit instructions to the mobile device, where a Device Owner Application operates to restrict the mobile device functionality. Mobile device functionality may be limited by restricting the mobile device's ability to send and receive text messages, email messages and phone calls; restricting the mobile device's ability to respond to user input; restricting the mobile device's ability to utilize a web browser; and restricting the mobile device's web browser from accessing predetermined web sites.
