Abstract: The neural network is trained to separate plural radio signals that substantially overlap in in frequency and time. A pair of processing pipelines receive the source audio signals and represent them in the complex I-Q plane to define first and second baseband representations. To these baseband representations are applied first and second rotating vectors, of rotational rate corresponding to first and second tuning offsets to define first and second training data which are then mixed to generate overlapping data training data, which are fed to the neural network to produce first and second estimated source signals. The neural network is trained from the overlapping data by maximizing a scale-invariant ratio comparing the first and second estimated source signals with the first and second source audio signals.

Abstract: In a wireless ad hoc network (20) of nodes (22), a method (64) of power management entails monitoring (82) a current traffic load of the network (20), and in response to the current traffic load, selecting (106, 132) a subset (102) of epochs (80) within cyclically repeating time windows (78) for network communication. A message (122) is communicated (120) between the nodes (22) in the network (20). The message (122) identifies the subset (102) of epochs (80) for using in communicating network traffic (32). Following receipt of the message, each of the nodes (22) modifies (124) a transmit capability mode by entering a run state (40) during the epochs (80) within the subset (102) to enable communication of network traffic (32) and by entering a low power consumption idle state (42) during the remaining epochs (80) within the time window (78).

Abstract: A flow of data (26) is regulated in a communication system (20). A data rate is established in each of a data source (24) and a data sink (28). The data (26) is transmitted by the data source (24) and written into a buffer (32) at the source data rate, then read from the buffer (32) and received by the data sink (28) at the sink data rate. The level (62) of data (26) in the buffer (32) is monitored, and a rate-control signal (74) is dispatched to either the data source (24) or sink (28) when it is determined the buffer data level (62) is decreasing or increasing while at a lower or upper data-level threshold (66, 68), respectively. One of the data rates is adjusted in response to a rate-control signal (74).
