Demo of zero-padding DFTs for 4F7 course (lecture 2): Spectrum of a single complex exponential added together

主要是讲v-blast的系统仿真程序，很全面，很有用，大家可以用用看(Is mainly v-blast system simulation program, very comprehensive, very useful, you can use to see)

说明：  研究能量受限的SWIPT无线通信网络中，基站采用MIMO多天线发送信号给用户节点，在有窃听节点的情况下，通过联合优化发射波束形成矢量、人工噪声协方差和接收PS比来最小化总发射功率，同时保证每个接收机的个体保密率和能量收集约束。(In the energy limited swipt wireless communication network, the base station uses MIMO multi antenna to send signals to user nodes. In the case of eavesdropping nodes, the total transmit power is minimized by jointly optimizing transmit beamforming vector, artificial noise covariance and receive PS ratio, while ensuring the individual confidentiality rate and energy collection constraint of each receiver.)

说明：  压缩感知重构信号的实例 压缩感知（Compressed sensing），也被称为压缩采样（Compressive sampling）或稀疏采样（Sparse sampling），是一种寻找欠定线性系统的稀疏解的技术。(An example of compressed sensing reconstruction signal)

UMTS turbo encoder simulimk

一个用matlab解决微分方程的例子，比较适合初学者(To solve a differential equation using matlab examples, more suitable for beginners)

说明：  产生伪随机码，长度是任意2的指数次，非常可靠的程序(can generate the presedorandom code, any length is OK)

该matlab程序仿真了旁瓣对消系统，旁瓣对消是自适应阵列处理的重要方面(The matlab simulation, the sidelobe cancellation system of sidelobe cancellation is an important aspect of adaptive array processing )

Computing the frequency response of SRRC filter

用SBL算法和卡尔曼滤波压缩感知算法实现雷达的一维距离像成像，并对两者进行了成像性能分析对吧(SBL algorithm and Kalman filter using compressed sensing algorithm for one-dimensional range radar imaging, and imaging performance analysis carried out both right)
