20080242827 | Method for producing omni-meta aromatic polysulfonamide fiber - The invention relates to a method of preparing omni-meta aromatic polysulfonamide fiber which comprises three steps of preparing spinning dope, wet spinning and post treating. The said step of preparing spinning dope comprises the following steps: (1) dissolving 3,3′-diaminodiphenyl sulphone in a polar organic solvent and cooling it to −20˜20° C.; (2) adding m-phthaloyl chloride of the same mole of the 3,3′-diaminodiphenyl sulphone to carry out a polymerization reaction; (3) then adding an inorganic base of the same mole of 3,3′-diaminodiphenyl sulphone to neutralize the hydrogen chloride produced during the polymerization reaction. The spinning dope thus prepared has a polymer solid content of 10%-20%. The fiber prepared according to the method in the present invention has a greatly improved crimpability, and evidently increased elongation at break comparing with the conventional aromatic polysulfonamide fiber, so that the spinnability of resultant yarn is improved. | 10-02-2008 |

20120039244 | METHOD AND DEVICE IN RSs OF JOINTLY PROCESSING AND A METHOD AND DEVICE IN BSs OF CORRESPONDING PROCESSING - According to a detailed embodiment of the invention, the RS implements the following operations by using each of M shift parameter groups: Based on M shift parameters in the group, shifting respectively M decoded bit streams and merge the M shifted bit steams to get a check bit stream. Consequently M check bit streams are obtained by using M shift parameter groups. Then the RS transmits M check bit streams to the BS. The BS has received the M uplink signals from mobile terminals before and makes the M check bit streams as the check information of those uplink signals in order to check them better and reduce error rate. By adopting the method and device proposed by the invention, it is ensured in the low SNR regime error user rate or error block rate is more ideal in multi-user detection in the BS. | 02-16-2012 |
