  • Publication number: 20020191681
    Abstract: A receiving circuit comprises an A/D converter which converts a receive signal to a digital signal having a first data format at a sampling rate corresponding to twice the spreading bandwidth of the receive signal, an analog front-end interface which converts the first data format of the digital signal to a second data format, a searcher which detects a phase of the digital signal having the second data format to perform a synchronization capture and outputs a timing signal, an interpolation filter which samples the digital signal having the second data format at a sampling rate different from the sampling rate of the A/D converter, a rake receiver which detects the synchronism of a signal outputted from the interpolation filter based on the timing signal and a demodulator which demodulates a signal outputted from the rake receiver.

  • Patent number: 6022990
    Abstract: The present invention relates to a novel catalyst composition and a novel process for synthesizing methyl acrylate from methyl formate and acetylene, in which methyl formate reacts with acetylene in the presence of a main catalyst comprising one or more compounds selected from RuCl.sub.3, Ni(CH.sub.3 COO).sub.2, NiBr.sub.2, NiI.sub.2, NiSO.sub.4, Ni(NO.sub.3).sub.2, PdCl.sub.2, CoCl.sub.2, Rh.sub.3 (CO).sub.12 and RhCl.sub.3, and the catalyst promoter comprising one or more compounds selected from CuSO.sub.4, NaI, KI and CH.sub.3 I, at a temperature of 120.about.240.degree. C., and under reaction pressure of 1.0.about.10.0 MPa, a molar ratio of methyl formate to acetylene ranges form 0.1:1 to 20:1. The yield of methyl acrylate may reach to 63%.
