ABSTRACT:
There is provided a PN (Pseudorandom Noise) hypothesis moving apparatus and method in a high speed searcher. In the PN hypothesis moving apparatus, a PN sequence generator system has a PN sequence generator for generating a PN sequence and a PN state register for storing information about a PN state. A correlation counter counts the number of correlations, and a comparator receives the output of the correlation counter, a correlation length, and a search speed, compares them, and provides a PN state saving point and a PN state loading point to the PN sequence generator system according to the comparison to change a PN hypothesis.
