现在我终于找到了一份,它以FUNCTION的形式,再现了OFDM映射,IDFT/DFT,同步(时间/频率同步)和信道估计,以及频率偏移的估计等一系列代码.希望大家能从中得到你需要的东西. (Now I finally found a copy of it to the form of FUNCTION, reproduces OFDM mapping, IDFT/DFT, synchronized (time/frequency synchronization), and channel estimation, as well as the frequency deviation of the estimated range of the code. I hope that everyone will be you need.)

这是应用ｍａｔｌａｂ模拟电容充放电的过程，编写一段程序，希望对大家有用。(This is the application matlab analog capacitor charging and discharging process, the preparation of a program, in the hope that useful. )

QAM16在通信系统中是一种简单的调制方式，可以提高频谱利用率，该程序可以恢复QAM16的星座图(QAM16 in a communication system is a simple modulation, spectral efficiency can be improved, the program can resume constellation QAM16)

基于MATLAB的平面度评定方法，介绍了计算方法(Based on MATLAB flatness evaluation method, calculation method introduced)

说明：  MATHCENTRER下载的雷达杂波仿真系统，非常有参考意义(MATHCENTRER download of radar clutter simulation system, meaning a very good reference)

【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.)
