| 20100318875 | Data Transmission Method and Equipment - The present invention discloses a data transmission method and apparatus. The method comprises: segmenting data to be transmitted into information file segments with a length of Tb bits; performing forward error correction (FEC) coding for Tb information bit sequences composed of bits in same positions in a plurality of continuous information file segments to generate Tb check bit sequences, putting each bit of the check bit sequences in the same position in the check file segments as the corresponding information bit sequences; and transmitting each of the information file segments and check file segments according to their order; the number of bits contained in the information bit sequences being less than or equal to the maximum length of K | 12-16-2010 |
| 20110007661 | DEVICE AND METHOD FOR INTERLEAVED ENCODING RS CODE - The present invention provides a device and method for interleaved encoding RS code, the RS code used being RS (N, K, S). The method comprises: firstly, writing the data in the data packets to be RS interleaved encoded into the information region of the RS code byte interleaver column-by-column in turn; then, constructing the data of each row of the check region based on the data written into the information region; finally, performing cyclic shifting processing on the data of the check region, and reading out the data of the check region in the RS code byte interleaver column-by-column in turn. The present invention can be used to improve the performance of the entire data packet outputted, thereby enhancing the reliability of the data link layer, by evenly spreading the areas with a filled value of 0 in the last column of the information region that is filled with valid information and by performing cyclic shifting processing on the data of the check region so that the data of that region offer larger time span and good diversity effect when outputted. | 01-13-2011 |

| 20080276719 | SPRING SUPPORTED LOWER CLAMPER FOR DIRECT TENSILE TEST - The present invention discloses a spring supported lower clamper for direct tensile test, comprising a lower connection member, a lower end cap for holding a sample, a lower chain for connecting the lower connection member with the lower end cap, and spring-type supporting means for supporting a broken-apart lower part of the sample formed during the tensile test and the lower end cap. During the tensile test, the sample, the lower end cap and the lower chain are supported by the spring-type supporting means. Thus the sample can be prevented from being broken abruptly when a tensile force in the sample reaches its maximum level, and the mechanical behavior after the maximum tensile force is reached can be measured. | 11-13-2008 |
