Direct sequence spread spectrum (DSSS) communication systems has been widely used in these years for its advantage of wide spectrum, low working Signal-to-Noise ratio (SNR), anti-interference, anti-multipath effect and capability of LPI and LPD. They are increasingly replacing conventional communication forms and obtaining extensively applications in modern military and commercial communication systems, for example, CDMA communication system, GPS , measuring and control system, satellite chain, identification of friend or foe and etc. Therefore, corresponding DSSS electronic counter technique becomes a big problem to solve in electronic warfare domain. DSSS electronic counter technique including blind detection, blind parameter estimation and spreading sequences estimation. For the issue of DSSS electronic counter technique of DSSS/QPSK signal damaged by strong additive white Gaussian noise (AWGN), the main research content in this dissertation as follow.

说明：  最短路径的Dijkstra算法程序。Dijkstra算法是典型最短路算法，用于计算一个节点到其他所有节点的最短路径。主要特点是以起始点为中心向外层层扩展，直到扩展到终点为止。Dijkstra算法能得出最短路径的最优解，但由于它遍历计算的节点很多，所以效率低。 　　Dijkstra算法是很有代表性的最短路算法，在很多专业课程中都作为基本内容有详细的介绍，如数据结构，图论，运筹学等等。 (The Dijkstra shortest path algorithm for the procedure. Dijkstra algorithm is a typical shortest path algorithm, used to calculate a node to all other nodes of the shortest path. The main characteristics is the starting point as the center outward expansion layers, until the end date be extended to. Dijkstra shortest path algorithm can arrive at the optimal solution, but because of its calculation of the node traversal, so inefficient. Dijkstra algorithm is very representative of the shortest path algorithm, in many professional courses in the basic content as described in detail, such as data structures, graph theory, operational research and so on.)

模糊控制器，应用于控制系统，例如倒立摆的控制中。(Fuzzy controller used in control systems, for example, the control of inverted pendulum.)

This function calculates displacement response at interfaces of an elastic multilayered medium to a vertically propagating unitary SV or SH elastic wave. The function can be used to calculate the displacement response in a layered soil profile. Transfer functions between interfaces can be easily calculated by division of the total (=upward+downward) displacement response on the corresponding interfaces.
