Design method of general-purpose and high-speed digital correlator LSI

This paper proposes a construction of a general-purpose high speed correlator LSI, aiming at applications to various problems such as digital signal processing and synchronization word detection. A general method of constructing the rearrangement circuit as well as the generation of a high-speed detection pulse are presented. They are important in the construction of a high-speed synchronization word detector, one of the major applications of the high-speed digital correlator. It was shown by experiment that the high-speed digital correlator has the feature that the parameters can be set in a flexible way according to the problem, and can operate up to 200 MHz by the one-chip structure (two-parallel processing).
