  • Publication number: 20090041145
    Abstract: A method to detect data transmitted from multiple antennas, said method comprising steps of: selecting a starting data block and calling it as previous data block; defining a set of indices of bits to be checked for possible flip in the previous data block as a check candidate set; applying update rule to obtain updated data block using the previous data block and the check candidate set, wherein the update is made in such a manner that change in likelihood is positive; checking if the updated data block and several consecutive previous data blocks are the same; if yes, declare the updated data block as the detected data block; if no, make updated data block as previous data block and repeat updation of data block.

  • Publication number: 20080087545
    Abstract: The present invention represents a radical departure from most conventional macro-scale batch processing methods employed to synthesize and coat colloidal nanoparticles. Synthesis and coating are in series and in-situ, obviating the need for numerous cumbersome, and often expensive intermediate-processing steps. In one embodiment, the invention is a method and apparatus for synthesizing colloidal nanoparticles. In another embodiment, the invention is a method and apparatus for enabling coating of colloidal nanoparticles using an electrophoretic switch for contacting and separating said colloid nanoparticles.
