International Classification:

H04L 2714

US Classification:

375324, 375326, 370310, 343893

Abstract:

A method for generating a reference signal from a modulated signal transmitted to a communications station that includes an array of antenna elements and spatial processing means including: separating from the signals received at the antenna elements a copy signal corresponding to the signal transmitted by a particular remote station using an initial spatial weight vector corresponding to the particular remote station; determining from the terminal copy signal a reference signal having substantially the same frequency offset and time alignment as the received antenna signals; and computing a new spatial weight vector by optimizing a cost function, the cost function using the received antenna signals and the reference signal. For demodulation, the method further includes extracting the symbols of the modulated signal.

H04B 7/00
H04B 1/00

US Classification:

4555621, 4552771, 455 631

Abstract:

This invention relates to a method and apparatus for transmitting a downlink signal from a communication station to one or more subscriber units to achieve a desired radiation level over a desired sector (e. g. , everywhere), the communication station including an array of antenna elements and one or more signal processors programmed (in the case of programmable signal processors) to weight the downlink signal according to one of a sequence of complex valued weight vectors. The method includes sequentially repeating transmitting the downlink signal, each repetition with a different weight vector from the sequence until all weight vectors in the sequence have been transmitted with. The sequence is designed for achieving the desired radiation level during at least one of the repetitions. In this way, every user in the desired region is transmitted to in the time period.

International Classification:

G01V 3/00

US Classification:

324307

Abstract:

The present invention discloses a method of simultaneously conducting more than one step of a radiofrequency phase cycle in a nuclear magnetic resonance (NMR) experiment. The method first involves providing a sample. Next, one or more radiofrequency pulses are applied to a plurality of spatially discrete slices of the sample under conditions effective to simultaneously conduct more than one step of a radiofrequency phase cycle in a single transient. Then, NMR signals generated from the step of applying the radiofrequency pulses are acquired. Finally, the NMR signals are processed to obtain an NMR spectrum.

International Classification:

G01V 3/00

US Classification:

324309, 324307

Abstract:

The present invention relates to a method for simultaneously conducting multiple steps of a cycle of a nuclear magnetic resonance (NMR) experiment without the use of pulsed magnetic field gradients during signal detection in which one or more spatially selective radiofrequency pulses are applied to a sample under conditions effective to simultaneously spatially distribute the radiofrequency power associated with each of the cycle steps to a plurality of spatially discrete sections within the sample such that each section executes an individual step of the cycle and the resultant NMR signals from each of the cycle steps are produced simultaneously.
