The Global Positioning System (GPS) precision code (P-code) was not originally designed for direct acquisition per se, but rather through the hand-over from its corresponding acquired coarse acquisition code (C/A code). Attempts have been made to design direct acquisition methods that do not first acquire C/A code by utilizing massive physical correlators in parallel for code search. In contrast to this "hard" parallelism, this paper considers the "soft" parallelism in which fast algorithms run over the same segment of data many times to cover all search parameters. As a continuation of our previous papers presented at ION-GPS'99 [Yang, Vasquez, and Chaffee, 1999a; 1999b], which introduced the novel concept of extended replica-folding technique, this paper presents the statistical analysis and computer simulation as means to quantify the performance of the technique.
