  • Patent number: 7586992
    Abstract: An apparatus and method for channel estimation and CP reconstruction in an OFDM-STBC mobile communication system are provided. An ISI canceller cancels ISI signal components from first and second received symbol sequences. A cyclicity restorer cancels ICI signal components from the ISI-cancelled first received symbol sequence and the ISI-cancelled second received symbol sequence. A recoverer acquires the recovered sequence estimates of the ICI-cancelled first received symbol sequence and the ICI-cancelled second received symbol sequence by decoding. The ICI cancellation of the ISI-cancelled first and second received symbol sequences and the ISI cancellation of the second received symbol sequence are iterated a predetermined number of times.

  • Patent number: 7587660
    Abstract: Multiple-access codes are generated using an asymptotically optimal decoding algorithm, such as the Viterbi algorithm. A trellis may be constructed using a number of desired users, at least one code length, and a number of code-chip parameters. A fitness function is derived from a mathematical relationship between the multiple-access codes, and may include some measure of correlation of the codes. The multiple-access codes correspond to paths having optimal path metrics derived from the fitness function. Multiple iterations through the trellis may be performed to refine a selection of multiple-access codes.

  • Patent number: 7585955
    Abstract: A process for separating a protein from a sample containing a mixture of proteins is disclosed. The process comprises forming an aqueous combination comprising the sample and an ion exchange material at a pH which is less than the pI of a first fraction of the proteins in the aqueous dispersion but greater than the pI of a second fraction of the proteins in the aqueous dispersion. The aqueous dispersion may then be intensely mixed, causing a fraction of the proteins in the combination to bind to the ion exchange material, and, optionally, centrifuged, causing the combination to stratify into a concentrated solids fraction and a supernatant, the supernatant containing the fraction of the proteins that did not bind to the ion exchange material. This process, including the steps of intense mixing and centrifugation, requires no expensive, specialized instrumentation, can be quickly performed, and is carried out in non-denaturing conditions, allowing for the separated proteins to be further studied.

  • Patent number: 7583379
    Abstract: Surface-enhanced Raman spectroscopic (SERS) systems and methods for detecting biomolecules of interest, such as a virus, bacterium, or other infectious agent, are provided. A spectroscopic assay based on surface enhanced Raman scattering (SERS) using a silver nanorod array substrate fabricated by oblique angle deposition has been developed that allows for rapid detection of trace levels of viruses or bacteria with a high degree of sensitivity and specificity. This novel and improved SERS assay can detect minor spectral differences within strains of a single virus type such as respiratory syncytial virus or influenza virus in the presence of biological media. The method provides rapid diagnostics for direct molecular and structural characterization of virus strains and virus gene deletion mutants generating reproducible viral spectra without viral manipulation.

  • Patent number: 7583082
    Abstract: In a first step of image formation by MRI or the like, a gridding convolution is performed for each coil using a Kaiser-Bessel kernel, so that each coil channel now contains data on grid points. In the second step, another 2D convolution is performed on each of the gridded coil data sets in either k-space or image space, and all the convolutions are summed up to produce the composite k-space data set for the target coil. In the third step, the composite data set is then transformed to form an un-aliased image for that coil. In the fourth step, the un-aliased images for all the coils are combined using square-root-of-sum-of-squares to form the final reconstructed image.
