模拟带噪声的匀加速直线运动，数据平滑，多个smooth函数的应用，简单易懂(Simulation with the noise of the constant acceleration of linear motion, data smoothing, multiple smooth function of the application, easy to understand)

an inferior assistant or a channel administrator hopes to append some additional message, such as the origin information, image notation or authentication data, within the encrypted image though he does not know the original image content. some parameters are embedded into a small number of encrypted pixels, and the of the other encrypted pixels are compressed to create a space for accommodating the additional data and the original data at the positions occupied by the parameters

运用分枝定界法求解混合整数规划的matlab程序( Use the branch and bound method for solving mixed integer programming procedures meaning of the of the input parameters: min f* x A* x < = b Aeq* x = beq iter_num_max: maximum number of iterations lb : each variable lower limit UB: upper limit of the each variable X0: Initial ID: 0,1 variable, ID (k) = 1 indicates the variable k is an integer variable, ID (k) = 0, represents the k variable non-integer variable ftemp_up: initial upper bound, unable to find the upper bound of the initial default is infinite IP: initial feasible solution, the initial feasible solution can not be found, the default is the empty output parameters meaning: x: y: optimal solution of the objective function value corresponding to the optimal solution time-consuming iter_num: the number of iterations of the entire branch and bound process Time: Run this program)

参考3GPP相关标准并根据LTE技术特征和关键特性，对下行链路级进行设计，包含以下步骤：比特生成、CRC校验、码块分割、编码、速率匹配、码块级联、加扰、调制、层映射、预编码、资源映射、OFDM符号生成和天线映射。为模拟无线传输信道，还需仿真相应的信道模型。收端则是发端的严格逆过程，对接收信号进行一系列处理，得到代表原始发送的信息并判决。(References 3GPP LTE technology standards and in accordance with characteristics and key characteristics of the downlink stage design, comprising the steps of: generating bits, CRC checksum, code block segmentation, encoding, rate matching, code block concatenation, scrambling, modulation , layer mapping, precoding, resource mapping, OFDM symbol generation and antenna mapping. Analog wireless transmission channel, the need to emulate the corresponding channel model. The receiving end is the inverse of the originator of the rigorous, a series of processing the received signal, the representation of the original transmitted information and judgment.)

这次上传的绝对是好东西，数值优化，关键是对不同函数进行运算。这次将无约束测试问题上传，可作为论文数值计算使用。注：本人本科毕业论文做的是无约束优化，研究生做的是结构方程(LISREL)、数值优化、蚁群算法，可以进行交流，联系QQ272958823(Test function for optimation!)
