Abstract: Technique for full-duplex transmission in many-antenna multi-user (MU) multiple-input multiple-output (MIMO) systems is presented in this disclosure. An estimate of a self-interference channel between a plurality of transmit antennas and a plurality of receive antennas is first obtained. A precoder for self-interference reduction is generated based on minimizing a self-interference power related to the self-interference channel that is present at the plurality of receive antennas. Transmission data are modified using the precoder by projecting the transmission data onto a defined number of singular vectors of the self-interference channel that correspond to the defined number of smallest singular values of the self-interference channel. Data are received in full-duplex mode via the plurality of receive antennas simultaneously with transmitting the modified transmission data.

Abstract: Techniques are disclosed for data flow graph node update for machine learning. A plurality of processing elements is configured within a reconfigurable fabric to implement a data flow graph. The nodes of the data flow graph include one or more variable nodes, and the data flow graph implements a neural network. N copies of a variable contained in a variable node are issued, where the N copies are used for distribution within the data flow graph, and where N is an integer greater than or equal to one and less than or equal to the total number of nodes in the graph. The N copies of a variable are distributed within the data flow graph. The neural network is updated based on the N copies of a variable. Results from the distribution are averaged. The averaging includes parallel training of different data for machine learning.

Abstract: Base stations for MIMO wireless systems embodying efficient channel estimation techniques. One illustrative embodiment includes: an array of multiple antennas to exchange uplink and downlink signals with spatially-distributed user terminals; multiple transmit chains, each coupled to one of the multiple antennas by a respective transceiver that also couples that antenna to a respective one of multiple receive chains; and a controller. Each of the receive chains opportunistically derives estimated uplink channel response coefficients from packet headers in the wireless uplink signals, and the controller determines a steering transform based at least in part on the estimated channel response coefficients. The transmit chains apply the steering transform to spatially-distinct downlink signals to produce antenna-specific downlink signals for each antenna in the array.

Abstract: An environment is described in which a processing system provides application-level usage information to users. In one scenario, for example, the processing system may provide personal usage information to a user who is operating a user device. The personal usage information itemizes the amount of data (and/or other resources) that has been consumed by each application run by the user device. In another scenario, the processing system may provide expected usage information associated with at least one candidate application provided by a marketplace system. The expected usage information describes an expected consumption of data (and/or other resources) by the candidate application upon running the candidate application by the user device. The processing system can tailor the expected usage information that it sends to a particular user based on user profile data. The user profile data describes a manner in which users operate applications.

Abstract: Techniques for ability enhancement are described. Some embodiments provide an ability enhancement facilitator system (“AEFS”) configured to enhance a user's ability to operate or function in a transportation-related context as a pedestrian or a vehicle operator. In one embodiment, the AEFS is configured perform vehicular threat detection based on information received at a road-based device, such as a sensor or processor that is deployed at the side of a road. An example AEFS receives, at a road-based device, information about a first vehicle that is proximate to the road-based device. The AEFS analyzes the received information to determine threat information, such as that the vehicle may collide with the user. The AEFS then informs the user of the determined threat information, such as by transmitting a warning to a wearable device configured to present the warning to the user.
