匹配追踪和正交匹配追踪，通过虚拟阵元进行DOA估计，针对EMD方法的不足,实现典型相关分析，GSM中GMSK调制信号的产生。(Matching Pursuit and orthogonal matching pursuit, Conducted through virtual array DOA estimation, For lack of EMD, Achieve canonical correlation analysis, GSM is GMSK modulation signal generation.)

IMPLEMENTATION OF WATERMARKING TECHNIQUE FOR HIDE THE SIX TEXT PAGES IN A COLOR IMAGE using in matlab sw

用Ziegler--Nichols整定公式来求P,PI,PID的个参数，其中Gc是校正器的传递函数,kp为比例系数， Ti为积分时间常数，Td为微分时间常数，输入参量vars为带迟滞--惯性环节模型的KT τ(With Ziegler- Nichols tuning formula to seek P, PI, PID' s parameters, which Gc is the corrector transfer function, kp is proportional coefficient, Ti the integral time constant, Td for the differential time constant, input parameters vars as with hysteresis- inertia model of the KT τ)

说明：  无线传感器网络路由算法，采用最短路径，先搜索节点的一跳范围的距离，再搜索两跳的距离，仿真效果良好。(Wireless sensor network routing algorithm, using the shortest path first jump of the scope of the search node distance, and then search for the two jump distance, simulation results were very good.)
