基于optisystem中的matlab元件设计的AM调制程序源代码(Optisystem based on the MATLAB component design of the AM modulation program source code)

说明：  计算卫星之间的可见性预测时间，输入为卫星六根数(Visibility prediction algorithm between satellites)

压缩感知中全变分（TV）重构算法，本程序主要用于图像重构(Total variation in the compressed sensing (TV) reconstruction algorithm, this procedure is mainly used for image reconstruction)

【转】协同过滤代码，用于推荐系统，包括基于项目和基于用户两种情况。实现基于用户和基于项目的协同过滤算法。 实验所用数据为MovieLens – a web-based movies recommender system with 43,000 users & over 3500 movies. 保存在ga.mat文件用，由于ga.test测试集过于庞大，全部用来计算的话耗时庞大，所以每次计算时随机选择部分，具体函数的使用请参照probar.m。我所得到的实验结果保存在results1-results8.mat里面。([Turn] collaborative filtering code for the recommended system, including project-based and user-based two cases. User-based and project-based collaborative filtering algorithm. Experimental data for MovieLens- a web-based movies recommender system with 43,000 users & over 3500 movies. Saved in ga.mat file with Because ga.test test set is too large, all used to calculate the time-consuming massive, so every time The calculated random selection portion, the use of the specific function, please refer to probar.m. I obtained experimental results are saved inside results1-results8.mat.)

说明：  地震波场是指有地震波传播的空间。本程序用于计算二阶精度规则网格，二维波场模拟。(Seismic wave field refers to the space where seismic wave propagates. This program is used to calculate second-order precision regular grids and two-dimensional wave field simulation.)

说明：  实现OFDM多种信道条件下的LS时域频域信道估计方法仿真(Simulation of LS time domain and frequency domain channel estimation method for OFDM with multiple channels)
