    摘要： The invention relates to a method and to a switching device (4) and a measurement system (1). In the method according to the invention for determining time differences between measurement signals measured by at least two couple measurement devices (2, 3), a time basis signal is first generated for the measurement devices (2, 3). A common reference signal is further generated by a signal generator (5). The common reference signal is fed to measurement signal inputs (8, 9) of the coupled measuring devices (2, 3) via the switching device (4). A measurement signal is then fed to said measurement signal inputs (8, 9) of the coupled measuring devices (2, 3) and the time position of the measurement signals relative to the reference signal is determined in each of the coupled measuring devices (2, 3). The switching device (4), to this end, has a first measuring device connection (12) and a second measuring device connection (13) connected to the measurement signal inputs (8, 9) of the first measuring device (2) and the second measuring device (3). A reference signal is alternately fed via the measuring device connections (12, 13) of the switching device (4) to the first or the second measuring device (2, 3) by connecting the first measuring device connection (12) to the reference signal input (22) or a first measuring connection (14), or by connecting the second measuring device connection (13) to the reference signal input (22) or the second measuring connection (15).

    摘要： A technique facilitates the monitoring of thermodynamic properties of reservoir fluids. The technique utilizes a modular sensor assembly designed to evaluate a sample of a hydrocarbon-containing fluid within a cell body. A variety of sensors may be selectively placed into communication with a sample chamber within the cell body to evaluate the sample at potentially high pressures and temperatures. The sensors may comprise a density-viscosity sensor located in-situ to efficiently measure both the density and viscosity of the sample as a function of pressure and temperature. Other sensors, such as an optic sensor, may also be positioned to measure parameters of the sample while the sample is retained in the sample chamber.

    摘要： A method and a device for synchronizing the carrier frequency of a carrier signal comprising a frequency offset and/or a phase offset. According to the invention, the method estimates the frequency offset and/or phase offset of the carrier signal by means of a maximum likelihood estimation from a received signal, which comprises temporally discrete, complex rotary indices, for which only the temporally discrete phases are dependent on the frequency offset and/or phase offset. An offset quadrature-modulated received signal is thus converted into a modified received signal comprising temporally discrete, complex rotary indices, for which only the temporally discrete phases are dependent on the frequency offset and/or the phase offset.

    摘要： A method and a device for determining an unabbreviated channel-impulse response in an OFDM transmission system, of which the duration is greater than the length of the guard interval, estimates the channel-transmission factor at frequency-time positions of a relatively-coarse frequency-time raster, interpolates the channel-transmission factor at frequency-time positions of a relatively-fine frequency-time raster and calculates the unabbreviated channel-impulse response by means of inverse Fourier transform from the estimated or interpolated values of the channel-transmission factor at the frequency-time positions of the relatively-fine frequency-time raster. In this context, estimated values of the channel-transmission factor optimized at the individual frequency-time positions of the relatively-fine frequency-time raster are determined from received symbols and from transmitted symbols estimated by means of decision from the received symbols.

    摘要： The invention concerns a procedure for the estimation of unknown parameters (Δω, Δφ, ε,gasync,gbcode) of a received CDMA-signal (rdesc(v)) which is transmitted by means of a transmission channel (11), in which the CDMA-signal has experienced changes to the parameters (Δω,Δφ,ε,gbsync,gbcode) with the following steps: (a) formation of a cost function (L), which is dependent on the estimated values (Δ{tilde over (ω)},Δ{tilde over (φ)},{tilde over (ε)}, . . . ) of combined unknown parameters (Δω,Δφ,ε, . . . ); (b) partial differentiation of the cost function in respect to the said estimate values (Δ{tilde over (ω)},Δ{tilde over (φ)},{tilde over (ε)}, . . . ) of the unknown parameters (Δω,Δφ,ε, . . . ); (c) formation of a matrix-vector-equationfrom the presupposition that all partial differentials of the cost function are zero and thus a minimum of the cost function exists, and (d) computation of at least some of the matrix elements of the matrix elements of the matrix-vector-equation with the use of the Fast-Hadamard-Transformation.
