A system and method for processing information in a data set that contains samples of at least two classes using an empirical risk minimization model, wherein each sample in the data set has an importance score. In one embodiment, the method includes the step of selecting samples of a first class being labeled with class label +1 and a second class with class label −1, from the data set, prescribing an empirical risk minimization model using the selected samples with an objective function and a plurality of constraints which adequately describes the solution of a classifier to separate the selected samples into the first class and the second class, modifying the empirical risk minimization model to include terms that individually limit the influence of each sample relative to its importance score in the solution of the empirical risk minimization model, and solving the modified empirical risk minimization model to obtain the corresponding classifier to separate the samples into the first class and the second class.

The subject matter disclosed herein relates to techniques for estimating a speed of an object that transmits a signal at a carrier frequency. An apparatus and method disclosed herein includes receiving at an array of multiple antenna elements a radio frequency signal transmitted by a moving object; and estimating a speed of said moving object based, at least in part, on a spatial cross-correlation among characteristics of signals received at individual ones of said multiple antenna elements.

Method and apparatus for uplink transmission using multiple antennas are disclosed. A wireless transmit/receive unit (WTRU) performs space time transmit diversity (STTD) encoding on an input stream of a physical channel configured for STTD. Each physical channel may be mapped to either an in-phase (I) branch or a quadrature-phase (Q) branch. The WTRU may perform the STTD encoding either in a binary domain or in a complex domain. Additionally, the WTRU may perform pre-coding on at least one physical channel including the E-DPDCH with the pre-coding weights, and transmitting the pre-coded output streams via a plurality of antennas. The pre-coding may be performed either after or before spreading operation.

Embodiments of the invention exploit cyclostationarity of linearly modulated signals, transmitted through fading channels, to provide robust blind and data-aided mobile speed estimators. Embodiments of the invention utilize at least two methods of cyclic-correlation- and cyclic-spectrum-based methods and extension to space-time speed estimation at the base station in macrocells. In comparison with background art methods, the new estimators of the embodiments of the invention can be used without any need for pilot tones, and are robust to additive stationary noise or interference of any color or distribution. In addition, embodiments of the invention can also be implemented blindly, which can increase the data throughput. Performance results of the estimators of the embodiments of the invention are illustrated via extensive Monte Carlo simulation results.

An Interactive Mobile Aquatic Probing and Surveillance system. The system includes a remote aquatic or amphibious agent which is controlled by a typically land-based computer host. The agent is a field robot in the form of a comparatively small and inexpensive, untethered, self-propelled, aquatic or amphibious, non-submersible vehicle that preferably carries physical and water characteristic sensors, as well as other operational equipment for use on relatively small bodies of water and wetlands. The host interacts with a human operator and provides control commands to and receives data from the agent in real time via a wireless communication between the agent and the host. The control commands include guidance commands including navigational and propulsion commands as well as commands for operating the sensors and various other equipment carried by the agent.
