70 results about "C-value" patented technology

C-value is the amount, in picograms, of DNA contained within a haploid nucleus (e.g. a gamete) or one half the amount in a diploid somatic cell of a eukaryotic organism. In some cases (notably among diploid organisms), the terms C-value and genome size are used interchangeably; however, in polyploids the C-value may represent two or more genomes contained within the same nucleus. Greilhuber et al. have suggested some new layers of terminology and associated abbreviations to clarify this issue, but these somewhat complex additions are yet to be used by other authors.

Method of adding cyclic redundancy code of transmission block

A method is provided for adding a cyclic redundancy check code to a transmission block. The method, based on the two-stage CRC coding scheme, comprises the following steps: step A1. judging whether the sum of the length of a transmission block and the length of Y-site CRC code is larger than the Turbo or the maximal code length of LDPC coder, if it is, going to the step A2, otherwise, that is the sum is smaller than or equal to the Turbo or the maximal coding length of LDPC coder, going to the step A3; step A2. performing Y-site CRC coding of the transmission block, and adding the coded Y bit CRC1 check code at the back of the transmission block; step A3. further dividing the transmission block into C code blocks to allow the sum of each code block and X-site CRC code length smaller than or equal to the Turbo or the maximal code length of LDPC coder, and the C value is set minimum; step A4. performing the X-site CRC coding of each code block, and adding the coded X bit CRC2 check code at the back of the code block; and step A5. performing the Turbo or LDPC channel encoding of the code blocks resulting from segmentation. The method can reduce the retransmission times of the upper layer, increaser the retransmission speed of the system and reduce the decoding complexity.
