设计弹出菜单利用 Visual basic 6.0 开发工具实现(Visual basic 6.0 )

说明：  这是个OFDM系统的算法，内部包含同步，信道估计等，而且用蒙特卡洛方法进行仿真分析。(This is an algorithm for OFDM systems, internal includes synchronization, channel estimation, and simulation analysis using the Monte Carlo method.)

仿真OOK载波调制信号在AWGN信道下的误码率和误比特率性能，并与理论值相比较。 OOK是ASK调制的一个特例，把一个幅度取为0，另一个幅度为非0，就是OOK。(OOK modulation signal simulation in AWGN channel bit error rate and bit error rate performance, and compared with the theoretical value. OOK is a special case of ASK modulation to an amplitude taken as 0, and the other non-zero amplitude is OOK.)

一种基于双簇头的能量均衡的无线传感器网络路由算法 (Wireless sensor network routing algorithm based on energy balance of the dual cluster head)

Matlab实现中值滤波与均值滤波的对椒盐噪声滤波的比较！(Matlab to achieve median filter and mean filter for noise filtering salt and pepper comparison!)

说明：  LSB是Least Significant Bit Substitution的简称，也叫最低有效位水印嵌入，(lsb watermarking embed)

matlab中产生16QAM信号 星座图(generate 16QAM signal )

将周期图、自相关、协方差、改进协方差、Burg五种谱分析法封装为函数，并调用之对三个不同的信号源进行谱估计。(Encapsuler 5 methods of spectrum uation (Periodogram, COR, COV, MCOV, Burg) as functions, and use them to do frequency uation of three different signals.)
