摘要： A satellite signal receiver apparatus by which the hardware scale can be suppressed while high speed synchronization is assured. A carrier frequency component is removed from a satellite signal. Then, adding those of signals obtained after every period interval of spread spectrum codes and signals stored in a memory which have a same phase at the period intervals and writing an addition result back into the memory are repeated by a number of times corresponding to plural periods thereby to accumulate signals corresponding to sums of the signals added over the plural periods at the period intervals into the memory. Then, correlation calculation is performed between the signals for the one period of the spread spectrum codes corresponding to the plural periods and a spread spectrum code of the receiver side to detect a correlation point between the satellite signal and the receiver side spread spectrum code.

摘要： In a signal processing apparatus a synchronizer acquires synchronization with the spreading code of an intermediate frequency signal converted from a signal received from a satellite in a global positioning system. A demodulator then demodulates a message contained in the intermediate frequency signal. A measuring unit outputs a primary signal to a predetermined signal line, the primary signal expressing positioning results for the apparatus as measured on the basis of the demodulated message. A secondary signal output unit attaches a predetermined header to a secondary signal and outputs the result to the predetermined signal line, the secondary signal containing at least the intermediate frequency signal, or a signal generated from the intermediate frequency signal.

摘要： A method for performing frequency analysis by executing discrete Fourier transform with a smaller capacity of a memory than in usual FFT processing, without reducing the frequency resolution. A-power-of-two NA=2a (where “a” is an integer) memories for discrete Fourier transform are prepared. A former-stage calculation step of taking out frequency components of an input signal having a-power-of-two NB=2b (where “b” is an integer and b>a) data items, in a comb manner and of calculating NA intermediate data items and a latter-stage calculation step of applying fast Fourier transform to the intermediate data items obtained in the former-stage calculation step, by using the NA memories for discrete Fourier transform are executed 2b−a times with the frequency components taken out in the comb manner being changed, to execute discrete Fourier transform through 2b−a operations.

摘要： A GPS receiver that is capable of acquiring a GPS signal from a plurality of GPS satellites efficiently and at a high speed, and that is capable of performing a positioning calculation with a high degree of accuracy. The FFT processing result of the addition result from the PN code, stored in the memory, is multiplied by the FFT processing result of the IF data (the received data), stored in the memory, and by inverse-diffusing this result, a correlative value is obtained. By repeating this process while changing the combination of the PN codes to be added, and the synchronization acquisition processing, by a plurality of PN codes, is performed quickly with only a small amount of processing based on these results.
