COFDM的matlab仿真框图，完整版。(Matlab simulation of COFDM in the diagram, the full version.)

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.

一种混合贪婪随机自适应搜索（GRACH）算法，用于解决单车辆段车辆路径问题(a hybrid Greedy Randomized Adaptive Search (GRASP) algorithm that solves a single depot vehicle routing problem)

TeagerKaiser Energy operator method has been explained with help of Matlab 2007a version. This method can be used in case of speech and voice processing as well as any kind of signal processing activities. This has been explained with multiple input signals. A noise has been added in order to explain the method s efficiency at last.
