| Abstract(in English) | We examined the speed-up of a coherent integration processing in a GPS (Global Positioning System) signal processing system that was high sensitivity without the assistance data. We devised a method obtains high sensitivity performance by coherent integration for all the combinations of the navigation message bits. This time, we suggested a method for limiting the search for the navigation message bit using the restriction between vectors by considering the operation data as a vector on the complex plane. We calculated that the amount of the operation that was the order of N multiplication of two in an old method was able to be operated by the N log N order in this method. Moreover, we examined application when this technique was achieved by using FPGA. |
