  • Publication number: 20240352163
    Abstract: Disclosed is a preparation method for a polytrifluorostyrene. The method comprises: (i) providing a pre-emulsion of a trifluorostyrene monomer and a non-perfluorinated fluorine-containing anionic surfactant, wherein based on the weight of the trifluorostyrene monomer, the amount of the non-perfluorinated fluorine-containing anionic surfactant in the emulsion is 0.1-5 wt %, the non-perfluorinated fluorine-containing anionic surfactant has the general formula: CF3(CFX)n-(CH2)m-(C6H4)o-M, where n is an integer of 1-7, m is an integer of 1-4, and o is an integer of 0-2; X is selected from —F, —CF3, —OCF3, and —FCF2C(CF3)2; and M is selected from a carboxyl group, a sulfo group or respective salts thereof; (ii) adding an initiator to initiate a microemulsion polymerization reaction of the trifluorostyrene monomer; and (iii) adding a coagulant for demulsification.

  • Patent number: 8862168
    Abstract: A base station device, method, and communication system are disclosed. The base station includes a covariance matrix obtaining unit forming a covariance matrix of an interference vector and a noise vector from received signals from multiple user equipment; a ratio calculation and comparison unit that calculates a relative ratio between the interference and the noise in the received signals based on the covariance matrix and compares the ratio with a predetermined threshold; an adjusting unit that reduces values of non-diagonal elements in the covariance matrix when the ratio is less than the predetermined threshold; an equalizer unit that performs equalization based on the covariance matrix using an Interference Rejection Combining algorithm when the ratio is greater than or equal to the predetermined threshold, and equalizes the received signals based on the adjusted covariance matrix using a Minimum Mean Square Error algorithm when the ratio is less than the predetermined threshold.

  • Patent number: 7818019
    Abstract: The present invention relates to technique for optimized assignment of Abis transmission resources based on dynamic statistical time division multiplexing, the method comprising the steps of: assigning a set of 64 k TS's to GPRS/EGPRS services on an Abis link, the set of 64 k TS's shared among all BTS's connected to the Abis interface; a PCU assigning sufficient Abis transmission resources to a TRX based on the load thereof if the TRX has EGPRS services; a BSC interconnecting Abis transmission resources and BSC-PCU transmission resources and informing a BTS that said Abis transmission resources have been assigned to a TRE mapped to the TRX; the PCU reassigning bandwidth of the Abis transmission resources based on changes in the load of the TRX; in each TRX, all RTS's statistical-time-division-multiplexing all transmission resources of the TRX based on flow in different periods for different RTS's.
