Abstract: An active sequential xampling receiver for spectrum sensing is disclosed. The receiver includes a dynamically adjustable analog front end to perform sub-Nyquist energy sensing across a broad radio frequency (RF) spectrum. In an exemplary aspect, the receiver includes a dynamic modulator which modulates the broad RF spectrum to dynamically select sub-bands (e.g., RF channels) and fold their spectral content into a narrower baseband signal for energy detection. A controller adjusts the dynamic modulator to maximize utility of the spectrum detection based on past energy observations.

Abstract: An operating configuration for a power system during a particular time period may be derived from a net load forecast for the power system during the particular time period. The operating configuration may be based on characteristics of power generation units (PGUs) available within the power system (e.g., power generators). The characteristics of a PGU may include a generation trajectory for the PGU that defines, inter alia, power generated by the PGU as the PGU ramps up power production within the power system. The generation trajectory of PGUs may be evaluated in view of the net load forecast to ensure that adequate power resources are available within the power system and avoid ramping scarcity conditions.

Abstract: Methods and systems for space-time coding for distributed cooperative communication.

Abstract: Data is transmitted from a source wireless device to a destination wireless device by: (a) discovering node-to-node wireless channel conditions in a wireless network; (b) determining at least one of (A) wireless relay devices, (B) modulation schemes, and (C) transmission rates using the discovered node-to-node channel conditions; (c) signaling at least some of the determined information to the determined wireless relay devices; (d) receiving, with each of the wireless relay devices, a transmission of the data from the source wireless device; and (e) transmitting, with each of the wireless relay devices, a randomized, space-time encoded, part of the received data, to the destination device using the signaled at least some of the determined information.

Abstract: Methods and systems for space-time coding for distributed cooperative communication.

Abstract: Methods and systems that enable a cooperative form of transmission performed by a set of asynchronous transceivers operating as a distributed joint communication system. In an embodiment of the method of this invention, information is transmitted from one or more predetermined nodes (the source nodes) in the network. The information is received at the other nodes (the receiving nodes) in the network. For every information symbol/codeword each of the receiving nodes receives an accumulation of signals from nodes transmitting an earlier stage. At each of the receiving nodes a predetermined criterion is utilized to decide whether to retransmit the received information. If retransmission is indicated, the signal modulating the information symbol is retransmitted from the receiving nodes and delivered to an increasing number of downstream nodes.
