摘要： The invention relates to supporting an acquisition of a signal, wherein the signal comprises a sequence of complex valued samples, wherein the acquisition comprises an integration of the complex valued samples in subsequent integration intervals, and wherein the signal may be subject to a frequency drift. In order to enable an improved acquisition, a phase angle is estimated in the signal in a respective integration interval (step 504). The samples are adjusted based on the estimated phase angle in a respective integration interval (step 505). Only the adjusted samples from a plurality of integration intervals are then integrated (step 507, 508).

摘要： For supporting a satellite based positioning of a mobile arrangement (30,40) with assistance data, a communication network converts parameters of a dedicated orbit model describing a movement of a satellite (50,60), which dedicated orbit model is defined for a particular satellite based positioning system, into parameters of a common orbit model describing a movement of a satellite (50,60). Alternatively or in addition, the network replaces a reference value that is based on a satellite based positioning system time in available parameters of an orbit model by a reference value that is based on a communication system time. After the parameter conversion and/or the reference value replacement, the parameters are provided as a part of assistance data for the satellite based positioning. Alternatively or in addition, a set of data is transmitted in one direction between the mobile arrangement and the communication network, which is independent of the employed positioning mode.

摘要： The invention relates to a method for determining the time of transmission of a signal part of a code modulated signal transmitted by a beacon of a positioning system and received by a receiver of the positioning system. In order to enable such a determination in week signal conditions, it is proposed that measured subcomponents of the time of transmission of at least two signal parts are compared with corresponding predicted subcomponents in a way resulting in a combined difference for all signal parts. The comparison is performed for a plurality of assumed errors in the predicted subcomponent. The accurate time of transmission of a signal part is then determined based on the determined error value which results in the smallest combined difference. The invention relates equally to a corresponding receiver and to a corresponding positioning system.

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 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.
