很实用的一个OFDM仿真程序，OFDM采用BPSK、QPSK、16QAM、64QAM4种调制方式。按照星座图，将每个子信道上的数据，映射到星座图点的复数表示，转换为同相Ich和正交分量Qch。(A very practical OFDM simulation program, OFDM the BPSK, QPSK, 16 qam, 64 qam4 kind of modulation method. According to the constellation diagram, each will be the data on the channel, the plural of constellation is mapped to a point, said into in-phase Ich and quadrature Qch. )

Decimation reduces the original sampling rate for a sequence to a lower rate, the opposite of interpolation. The decimation process filters the input data with a lowpass filter and then resamples the resulting smoothed signal at a lower rate.

函数回调实例。用M文件可以更好的把握整个程序的全局，更能方便的实现函数回调。(Function callback instance. M-file can be used to better grasp the overall situation of the whole process, more convenient to implement the function callback.)

一个四维状态、二维观测的目标跟踪扩展卡尔曼滤波程序，附有详细的说明。(a four-state, two-dimensional observation of the target tracking extended Kalman filtering process, with detailed explanations.)

mvdr算法是最小方差无畸变响应波束形成器，它的原理来自是使非期望波达方向的任何干扰贡献的功率最小，但又能保持观测方向的信号功率不变。(mvdr algorithm is the minimum variance beamformer response distortion, its principle is that any interference from the direction of arrival of the undesired contributions to a minimum power, but the power of the signal while maintaining constant observation direction.)

直序扩频系统，首先基带信号通过脉冲成型，m序列扩频然后进行BPSK调制发送，接收端接收到信号加干扰和噪声，进行解调和解扩恢复原始信号。( The straight foreword wide frequency system, the first baseband signal through the pulse formation, the m sequence wide frequency then carries on BPSK the modulation transmission, the receive termination receives the signal to add the disturbance and the noise, carries on the demodulation and the despread restores the primary signal. )
