    摘要: A communications network which is capable of effectively and efficiently handling fading between mobile wireless user terminals of a packet-switched network with minimal overhead and packet loss, and a method for using the same. The communications network employs an origination mobile terminal and surrounding macroscopic mobile terminals and/or surrounding fixed infrastructure. Communication is established between the origination mobile terminal and surrounding macroscopic mobile terminals and/or surrounding fixed infrastructure. The communication is established via modified request to send (RTS) and clear to send (CTS) messages, wherein the modified messages provide for an additional two sets of k unicast addresses where k equals the maximum number of routes available per route entry in the origination mobile terminal's route table.

    摘要: A system and method for efficiently and effectively simulating hardware-in-the-loop testing of a wireless communications network. The system and method employs an optical matrix-vector multiplier (MVM) for performing optical signal processing to simulate radio frequency (RF) signal propagation characteristics in a mobile wireless communications network. Specifically, the system and method employs an optical modulator, which is adapted to modulate optical energy with signal energy, such as radio frequency (RF) signal energy, propagating from a first group of transceivers of the network to form a vector of optical signals. The optical matrix-vector multiplier (MVM) receives the vector of optical signals, and has a matrix of optical channel weights which are modifiable in accordance with desired parameters to represent at least on parameter of the wireless network. The optical MVM is further adapted to output signals based on the received vector of optical signals and the optical channel weights. The system and method further employs a detector device, adapted to detect the output signals and to provide the output signals as an output vector of signals to a second group of transceivers of the network.

    摘要: Processing methods and associated hardware architectures for the spatio-temporal processing of phased array sensor signals are disclosed. The processing method employs a joint spatio-temporal domain processing approach. The disclosed method is an optimal estimation scheme which exhibits significantly reduced computational burden. Suppression of interference sources at angles-of-arrival other than the desired signal is achieved implicitly. The associated system architecture provides not only the ability to achieve good joint angle-Doppler estimates, but offers the ability to easily trade the relative performance in each domain. The disclosed approach emphasizes the use of multiple hypothesis testing with spatio-temporal whitening filters.

    摘要: The invention is directed to a method and associated system for the detection of various physiological features in multichannel sensor data. Truth data organized in the form of a vector sequence is used to generate a multichannel state variable model for data that is known to lack physiological features of interest. Such state variable models are obtained using one or more of a host of system identification algorithms. Upon identification of the model parameters, a multichannel inverse filter is derived from the model parameters. The inverse filter can be used to whiten or decorrelate components of sensor data sequences that are not associated with the physiological features of interest. The unwhitened output of the inverse filter then represents the physiological features of interest that can be extracted from the concomitant white noise. On this basis, a number of such filters can be produced for a variety of undesired physiological feature components of the data that occur separately or in combination. The invention is useful for the extraction of known and unknown features of interest from multichannel physiological sensor data.

    摘要: Apparatus and method for improving the detection of signals obscured by either correlated Gaussian or non-Gaussian noise plus additive white Gaussian noise using Estimates from multi-channel data of model parameters that describe the noise disturbance correlation are obtained from data that contain signal-free data vectors, referred to as “secondary” or “reference” cell data. These parameters form the coefficients of a multi-channel whitening filter. A data vector to be tested for the presence of a signal passes through the multi-channel whitening filter. The filter's output is then processed to form a test statistic. The test statistic is compared to a threshold value to decide whether a signal is “present” or “absent”. Embodiments of the apparatus and method include estimating the signal amplitude both implicitly and explicitly and calculating test statistics for signal detection in both Gaussian and non-Gaussian noise.

    摘要: A light projection tag system provides for the detection of spatially coincident light patterns projected by competing players on a gaming surface. Each player is equipped with an optical transceiver with a field-of-view that is geometrically coincident with the light pattern projected from the transceiver. Each player's transceiver can detect when an opponent's light pattern, also projected on the gaming surface, enters this field-of-view thereby achieving a tag. Detection methods include the use of modulated visible or infrared light. Various embodiments of the system include automatic targets and projected gaming mazes.
