Abstract: A coded signal is received via a physical channel. The coded signal is encoded by a parity check matrix. In some examples, the coded signal is low density parity check-encoded. The coded signal is decoded to determine a result signal. Said decoding alternatingly updates, for each one of a number of iterations, bit node values representing bits of the result signal and check node values representing constrains of the parity check matrix. In some examples, the decoding determines the result signal at a first precision and updates at least partly at a second precision which is lower than the first precision. In further examples, the number of iterations is dynamically adjusted.

Abstract: The present invention is directed to methods and compositions for blocking the effect of the intronic inhibitory splicing region of intron 7 of the SMN2 gene. The compositions and methods of the instant invention include short oligonucleotide reagents (e.g., oligoribonucleotides) that effectively target sites in the SMN2 pre-mRNA, thereby modulating the splicing of SMN2 pre-mRNA to include exon 7 in the processed transcript. The short target regions are 8-mers and 5-mers and also include the identification of a single nucleotide base that is essential for initiating a long distance stearic inhibitory interactions as well as novel targets distant from intron 7 which block the intronic inhibitory splicing of the same. These short target regions and concomitant inhibitory blocking oligonucleotides are less expensive and easier to manufacture and are small enough to cross the blood brain barrier.

Abstract: Systems and methods for processing data signals are described. In one implementation, a demodulator and a first decoder unit, such as a convolutional encoder or a quadrature amplitude modulation decoder, for receiving the output of the demodulator, decoding the second level of encoding and outputting a decoded signal and a first error indication signal indicative of errors in the decoded signal are provided. The decoded signal may be passed through a de-interleaving unit to form a de-interleaved signal. The first location signal may be passed to an identifier unit which receives it, and from it produces a second error indication signal indicative of the errors in the de-interleaved signal. The de-interleaved signal and the second error indication signal may be transmitted to a redundancy decoder, where the signals may be used to perform redundancy decoding.

The method also includes performing a first search for determining a first set of possible pulse positions for the pulses in the codevector. The method further includes performing a second search for determining a second set of possible pulse positions for the pulses in the codevector. In addition, the method includes forming the codevector using the first and second sets of possible pulse positions.

Abstract: A multi-tone synchronous collision resolution system permits communication nodes within a MANET to contend simultaneously for a plurality of available channels. The communication nodes contend for access using a synchronous signaling mechanism that utilizes multiple tones in a synchronous manner to resolve contentions. Contentions are arbitrated locally, and a surviving subset of communication nodes is selected. The communication nodes of the surviving subset then transmit data packets simultaneously across the available communication channels.

Abstract: The present invention is directed to methods and compositions capable of blocking the inhibitory effect of a newly-identified intronic inhibitory sequence element, named ISS-N1 (for “intronic splicing silencer”), located in the SMN2 gene. The compositions and methods of the instant invention include oligonucleotide reagents (e.g., oligoribonucleotides) that effectively target the SMN2 ISS-N1 site in the SMN2 pre-mRNA, thereby modulating the splicing of SMN2 pre-mRNA to include exon 7 in the processed transcript. The ISS-N1 blocking agents of the invention cause elevated expression of SMN protein, thus compensating for the loss of SMN protein expression commonly observed in subjects with spinal muscular atrophy (SMA).
