摘要： A method is described for determining a time offset of a CDMA signal incurred during transfer. For each of a plurality of time offset estimates, the received chip sequence is multiplied with a conjugate complex scrambling code that is shifted by a number of chips according to one of the time offset estimates; the chip sequence is despreaded based on a spreading code of at least one selected data channel to produce a symbol sequence, and an estimated amplification factor is determined by summation of an amount of the symbol sequence. The maximum of the amplification factors for the time offset estimates when a selected data channel is active, or the minimum of the amplification factors for the time offset estimates when the selected data channel is not active is then determined.

摘要： An Aided Location Communication System (“ALCS”) is described that may include a geolocation server and a wireless communication device having a GPS section where the GPS receiver section is capable of being selectively switched between a standalone mode and at least one other mode for determining a geolocation of the wireless communications device. An Aided Location Communication Device (“ALCD”) is also described. The ALCD includes a position-determination section having a GPS receiver and a communication section where the position-determination section is selectively switchable between a GPS-standalone mode and at least one other mode for determining a geolocation of the ALCD.

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.
