一份matlab的ppt教程，给初学者，比较多面地介绍了matlab的基础(The ppt of a matlab tutorial for beginners, more multi-faceted introduction to the basis for matlab)

说明：  利用最小总错误概率准则设计检测器的程序，计算最佳门限，研究门限在一定范围内变化时，Pe随门限变化的情况，给出Pe~ 曲线，对模拟结果进行分析。程序有注释。 (Use of design guidelines for minimizing the probability of error detection procedures, calculate the best threshold of threshold changes in a certain range, Pe threshold changes with the situation, given Pe ~ curve analysis of the simulation results. Procedure notes.)

lstm网络的建立、训练及应用实例，测试过，可用。(LSTM network establishment, training and application examples, tested, available.)

说明：  k-means算法实现以及Iris数据集(Implementation of K-means algorithm and Iris data set)

数字信号处理实验大全，从基础到充实，这里全有。(digital signal processing using matlab,lab source code.practical!)

这里面有两个程序，两个都是采用4QAM调制。不过个人觉得第一个更容易懂，因为写的很有条理。我改的那个程序就是根据这个来的。 不过在这里面有个问题就是信道系数只能是由高到低，大家可以试试，改成[0.227 0.46 0.688 0.46 0.227]这个是老师给我的仿真中常用的信道系数，这个成为归一化信道，就是系数平方和为1. 第二个程序没有涉及到信道系数，但是这个程序当中，在128个子载波中，前后有32个空载波，这个在OFDM中也是经常用的，这样可以降低误码率。 (And there are two programs, two are based on 4QAM modulation. But personally feel that the first is easier, because the writing is organized. I changed that procedure is based on the past. However, there is a problem in that there is only channel coefficients from high to low, we can try and change into [0.227 0.46 0.688 0.46 0.227] This is the teacher gave me the simulation channel coefficient commonly used, this became normalized channel, is coefficient of the square and is 1. The second program is not related to channel coefficients, but this program which, in the 128 sub-carriers, the before and after the 32 air carriers, the in OFDM is also often used, which can reduce the error rate.)
