UR旋转矢量转化，转化为RPY坐标，更加适合编程，非常靠谱(UR Rotation Vector Conversion)

利用数据板卡进行数据采集，利用半满的方式将模拟量转换成数字量(Data card for data acquisition, the use of half-full way to convert analog into digital)

说明：  FBMC框架的搭建，和OQAM+PPN多项滤波器，大概框架都有(The construction of fbmc framework and OQAM + PPN multiple filters, probably all of them have)

用Q-Learning实现中继选择，选择最佳中继进行通信传输(Realization of Relay Selection with Q-Learning)

说明：  ：载波频率偏移是OFDM系统实现的关键问题之一。分析了OFDM 系统载频偏移估计的2 种算法，即利用循环前缀和训练序列方法。它们均为最大似然估计方法。分别讨论了它们的基本 思想、实现方法和仿真结果。可以看出基于循环前缀算法复杂度较小，精度不高，而基于训练序列 的算法有较高的估计精度，但降纸了系统传输效率。(Abstract：Carrier frequency ofset is one of the key problems in OFDM system．Two foundational methods 。cycling prefix—based and training sequence—based algorithms。to estimate OFDM carriers~equency ofset are analyzed．Then it discusses their basic thoughts。implementing methods and simulation resuits． Finally。merits and demerits of every algorithm are supposed．It concludes that the cycling prefix— based algorithm has less complexity and less precision。and that the training sequence—based algorithm has better estimation performance at the cost of transmission efficiency．)

使用周期图法进行谱估计，主要使用自相关算法和直接法(We use the periodogram method to estimate the spectrum, mainly using autocorrelation algorithm and direct method.)

无线手机使用的集成式功放器/淤波器前端The use of wireless mobile devices, integrated power amplifier / silt-wave front-end(The use of wireless mobile devices, integrated power amplifier/silt-wave front-end)

说明：  基于matlab的QPSK调制与解调程序(QPSK modulation and demodulation)
