西安电子科技大学精品课程——数字信号处理.《数字信号处理教程——MATLAB释义与实现》 本教程系统地讲解了数字信号处理的基本理论和方法，注重物理概念的阐述，尽量把MATLAB的多媒体功能用于图形、动画和声音等形象的演示，是一本自始至终使用MATLAB来阐述问题和进行计算的数字信号处理教材。(Xi' an University of Electronic Science and Technology Courses- digital signal processing. " Digital signal processing tutorial- MATLAB interpretation and implementation" of the tutorial system to explain the basic theory and methods of digital signal processing, focusing on elaborate physical concepts, try to MATLAB multimedia functions for graphics, animation and sound, and image presentation, is a problem throughout to illustrate the use of MATLAB to calculate and digital signal processing materials.)

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.
