基于matlab的ofdm系统仿真，通过仿真实现了ls 和LMMSE准则的信道估计，并仿真比较了两种方法的性能(Matlab ofdm systems based on the simulation, the simulation criteria to achieve the ls and LMMSE channel estimation, and simulation performance of the two methods compared)

simulation of ofdm with diversity

细胞边缘检测，带测试图片，matlab实现，效果不错(Cell edge detection, with the test picture, matlab achieved good results)

this is bldc simulink file in matlab and sensorlles method for starting.

带约束条件的梯度投影法matlab程序，经过实测，可以使用(With the constraints of the gradient projection method matlab program, after the measurement, you can use)

基于自适应多尺度数学形态学的信号去噪，程序可以直接运行。(signal denoising based on adaptive multi-scale mathematical morphology )

说明：  快速迭代收缩阈值算法，FISTA用一种更为聪明的办法选择序列{xk}，使得其基于梯度下降思想的迭代过程更加快速地趋近问题函数F(x)的最小值。FISTA的缺点是：Lipschitz常数L(f)不一定可知或者可计算。(Fast iterative contraction threshold algorithm, FISTA uses a more clever method to select the sequence{xk}, making its iterative process based on the gradient descent idea more quickly approach the minimum value of the problem function F(X). The disadvantage of FISTA is that the Lipschitz constant L(f) is not necessarily known or computable.)

说明：  通过第一个rbm，依次训练后续的rbm,最终完成DBN 的训练(Through the first RBM, train the following RBM in turn, and finally complete the training of DBN)

OFDMA上行链路频偏干扰消除的所有算法总结 都是很经典的算法(OFDMA uplink frequency offset interference cancellation of all algorithms is very classic algorithm summary)

本程序是用于根据当地坐标信息来计算UTM坐标的转换程序，可能根据经纬高信息转换到当地的UTM坐标(This procedure is used for the conversion process according to the local coordinate information to calculate the UTM coordinates, according to latitude and longitude information may be converted to the UTM coordinates)
