Correlation pulse generating circuit in a spread spectrum receiver |
摘要 |
A spread spectrum receiver is disclosed in which a correlation pulse generating circuit for generating a correlation pulse from a correlation spike outputted by a correlator comprises an A/D converting circuit which A/D-converts said correlation spike; an absolute value detecting circuit for detecting the absolute value of the output of said A/D converting circuit; a peak value detecting circuit for detecting the value corresponding to a peak of the output of said peak value detecting circuit; a threshold value setting circuit for generating a threshold signal based on the output of said peak value detecting circuit; and a comparing circuit for comparing the output of the absolute value detecting circuit with said threshold signal to generate the correlation pulse.
