Second, we discuss the correlation properties and the hamming correlation properties of a number of trace function generation sequences by using systematic ways. we calculate the correlation function of generalized trace function sequences which include no sequences > kasami sequences and kumar - moreno sequences, and we also calculate the hamming correlation function of no sequences ^ kasami sequences and kumar - moreno sequences. at last, we degine the frequency - hopping sequences with optimal hamming correlation properties
其次，用較為統一的工具去研究各種跡函數生成序列的相關特性與hamming相關特性，求出了更廣意義下跡函數生成序列的相關函數，這類序列包括了no序列、 kasami序列與kumar - moreno序列；同時求出了no序列、 kasami序列和kumar - moreno序列的hamming相關函數值，研究發現某些具有良好相關特性的跡函數生成序列未必具有良好的hamming相關特性；最後，構造了具有最佳hamming相關性能的跳頻序列族。 -
Analysis of capacity of spread spectrum random access communication system spread with kasami sequences
序列隨機多址擴頻通信系統的容量分析 -
The sidelobes characters of the pn codes modulated by signals are discussed taken m - sequence and kasami sequence as examples in this dissertation. it can raise the mainlobe - sidelobes ratio when the initial phase is properly chosen. the mainlobe - sidelobes ratio can even be further improved when mismatched filters are adopted
本文第二章從國防重點型號裝備研製項目「北斗一號」用戶機的應用需求，以m序列和kasami碼為例，研究了有符號調制的偽隨機序列的旁瓣特性，指出通過選擇合適的偽隨機序列的調制初相，可以明顯的改善主旁瓣比；失配接收可以進一步提高主旁瓣比。
