<p>PROBLEM TO BE SOLVED: To increase the processing speed of signals without causing any large increase in power consumption, to improve the signal processing quantity and information transmission amount, and to process signals of multiple series by the same circuit in a correlator and a matched filter. SOLUTION: This correlator 1 is equipped with a signal delay block 2 which delays pieces of analog signal input data different in signal input time behind their input time and outputs them, a correlator unit 3 in which four stages of correlation cumulative quantizers 6 for finding cross-correlation between the analog signal input data from the signal delay block 2 and codes are connected in a pipeline shape, a code generation block 4 which outputs the code to the respective correlation cumulative quantizers 6, and an output process block 5 which integrates partial correlation values outputted from the correlation cumulative quantizer 6 in the 4th stage as the final stage of the correlator unit 3 and finds one correlation value from the integrated value.</p> |
