摘要： A method for determining a boundary of an information element, in which a repetition coded signal transmitted by satellites is received, which signal is modulated with information elements. A group of symbols forms one information element. A group of reference values are formed on the basis of the received signal. Of these reference values at least one vector is formed wherein the number of the elements corresponds to the number of symbols use in the transmission of the information element. A determination vector is formed on the basis of the at least one vector, whereafter the greatest of the elements of the determination vector is searched. The index of said elements indicates the boundary of the information element.

摘要： A method for performing an acquisition to a code-modulated spread spectrum signal comprises receiving the transmitted signal, sampling the received signal to form samples, forming at least one reference code corresponding to a code used in the modulation and forming a non-coherent search matrix on the basis of said samples. The non-coherent search matrix comprises elements in at least a first and a second dimension. The first dimension of the non-coherent search matrix represents the same frequency deviation but different code phases of the received signal, and the second dimension of the non-coherent search matrix represents the same code phase but different frequency deviations of the received signal. Each element is addressable in the first dimension by a first index and in the second dimension by a second index.

In order to reduce the total memory size required for such correlations, the method comprises storing signal samples of the at least one received code modulated signal with a first rate in a memory. The stored signal samples are then read with a second rate from the memory for determining a correlation between the read signal samples and samples of the at least one available replica code, wherein the second rate is higher than said first rate. The disclosure relates equally to a corresponding electronic device, to a chip for such an electronic device, to a system comprising such an electronic device and to a corresponding software product.

摘要： A system architecture for a receiver to process multiple signals on a common carrier frequency from a satellite. The receiver is arranged such that the receiver receives input data transmitted from the satellite. A pilot signal is tracked from the input data using a correlation channel, and a data signal is tracked from the input data using a data code generator operatively connected to the correlation channel. In one embodiment of the invention, the data signal generator creates replica code for the data signal. In another embodiment of the invention, the system can switch between the data signal generator and pilot signal generator based upon the signal-to-noise ratio of the incoming signal.

摘要： The present invention provides a method for a multi-path detection analysis and selectivity of CDMA signals using spread spectrum receivers using a correlation technique. The invention is based on determining by the spread spectrum receiver whether a distortion of a received radio frequency signal, caused by a multi-path component of said received signal, meets a predetermined condition using a pre-selected correlation analysis of said received signal. This invention is generally applicable to global navigation satellite system (GNSS) receivers and it is particularly useful in GNSS receivers, such as GPS (global positioning system) and Galileo receivers. The important goal of this invention is to provide a simple method for identifying signals that are corrupted by multi-path effects, and can be excluded from position calculation in the GNSS receivers.
