摘要： The invention relates to a method for performing an acquisition to a code- modulated spread spectrum signal. The method 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, forming a non-coherent search matrix on the basis of said samples. Said non-coherent search matrix comprising elements in at least a first and a second dimension. The first dimension of said non- coherent search matrix represent the same frequency deviation but different code phases of the received signal, and the second dimension of said non-coherent search matrix represent 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. The method further comprises determining a frequency shift of the transmitted signal and a code phase of the code used in the modulation on the basis of values of elements of said non-coherent search matrix. Said determining comprises defining at least one statistical parameter for at least one line of elements of said non-coherent search matrix in the first dimension on the basis of values of each element of said at least one line of elements, defining a reference value on the basis of a value of an element of said line of elements and said at least one statistical parameter, and examining the reference value to determine whether said element of said line of elements corresponds to the frequency deviation and the code phase of the received signal. The frequency deviation and the code phase of the received signal are determined on the basis of the indices of such element corresponding to the frequency deviation and the code phase of the received signal. The invention also relates to a receiver, a module, a system and a computer program product.

摘要： The invention relates to determining a correct code phase of a received, code modulated carrier signal using a correlation portion, a frequency compensation portion, a coherent memory and a non-coherent memory. In order to compensate for a code Doppler effect and/or a carrier Doppler drift effect, a mapping portion maps correlation values either to the coherent memory or to the non-coherent memory. Alternatively, the mapping portion maps correlation values stored in the coherent memory or in the non-coherent memory to new positions. The mapping depends on a frequency compensation applied by the frequency compensation portion and elapsed integration time, and/or on a drift of a frequency offset in correlation values output by said correlation portion.

摘要： The invention relates to the acquisition of a code modulated signal, wherein a first set of correlation results for correlations between the code modulated signal and a first replica code with different code phases and a second set of correlation results for correlations between the code modulated signal and a second replica code with different code phases are available. In order to achieve a high sensitivity, results from both sets of correlation results are combined (steps 304, 305, 306), wherein correlation results used in the combination are selected based on information on a relative difference between a correct code phase for both replica codes. Then, it is determined (steps 307) based on the combination whether at least one of the sets of correlation results comprises a correlation result representing the correct code phase for the first replica code or the second replica code, respectively.

摘要： The invention relates to method for validating detected code modulated signals transmitted by beacons of a positioning system and received by a receiver. In order to enable such a validation, it is proposed that the method comprises as a first step performing measurements for the detected beacon signals. Then, at least one of the detected beacon signals is selected as calibration signal. In a next step, at least one allowed range for results of measurements for detected beacon signals other than said calibration signal are determined based on measurements for the detected calibration signal and on an available reference position of the receiver. Finally, each detection of a beacon signal for which results of performed measurements are outside of an allowed range is rejected. The invention relates equally to a corresponding receiver, to an electronic device comprising such a receiver, to a device cooperating with such a receiver and to a corresponding positioning system.

摘要： The present invention provides a method for a flexible multimode operation of spread spectrum receivers, e.g., global navigation satellite system (GNSS) receivers, using a shared circuitry hardware configuration of the receiver for processing of different types of code division multiple access (CDMA) signals. According to said method the receiver utilizes shared channel circuitry to receive signals of different CDMA types providing a flexible multimode operation. The present invention provides a way to select the received signal type for each channel by replacing the dedicated channels with multimode channels suitable to multiple types of receiver signals. The multimode receiver is more flexible to operate in varying reception conditions. By utilizing shared channel circuitry the hardware size is kept small.

摘要： A method and apparatus for coding successive pitch periods of a speech signal. Base on a priori knowledge of statistical properties of successive speech periods, a shaped lattice structure is designed to cover the most probable points in the pitch space. The codebook index search starts with finding an open-loop estimate in the pitch space considering all dimensions and refining the open-loop estimate in a closed-loop search separately in each dimension based on the shaped lattice structure. The closed-loop search for the first subframe is for obtaining an absolute pitch period or a delta pitch while the closed-loop search for each of the other subframes is for obtaining a delta pitch for the respective subframe.
