Code Sequence Performance Analysis Using Cross-Correlation Parameters in Phase-Coded Multiple Access Communication Systems.

Abstract

This thesis documents a technique to compare cross-correlation parameters of binary sequences used for spread-spectrum multiple-access radio communication systems, by performing a thresholding process on the correlation functions. The performance of Maximal length, Gold and Kasami code sequences is measured and analyzed for code lengths ranging from 63 to 1023. Comparisons of optimized codes versus unoptimized codes for each type of code sequence are analyzed in terms of the thresholding process. Comparisons are made of the performance of code sequences and code sets at lengths of 63, 127, 255, and 1023. The software used to analyze the codes is discussed in terms of structure and performance, and is included as appendices in the thesis. The results of this investigation indicate that the thresholding process can be used to evaluate binary sequence performance. Additional keywords: pseudo noise systems; plotting. (Author)
