本教程使用的DSP库来自ARM官方，此库支持以CM0，CM3，CM4以及CM7为内核的所有MCU。本期教程开始带领大家学习DSP教程，学习前首相要搞明白一个概念，DSP有两层含义，一个是DSP芯片也就是Digital Signal Processor，另一个是Digital Signal Processing，也就是我们常说的数字信号处理技术。本教程主要讲的是后者。( This tutorial uses a DSP library the ARM official, this library supports CM0, CM3, CM4 and CM7 for the kernel of all MCU.)

通信中，非常经典的注水算法的代码，在OFDM中子载波，功率分配中调用(Communication, very classic water algorithm code, in the neutron-carrier OFDM, power allocation call)

说明：  对当前通信信号中常用的数字调相信号BPSK、QPSK、1／4一QPSK、8PSK的调制识别问题，提出了一种基于信号差分高阶累积量的识剐算法。该算法分两个层次进行调制识别，首先利用信号的四阶累积量特征对BPSK、QPSK和{1／4一QPSK、8PSK}信号进行识别，然后再利用信号差分的四阶和八阶累积量特征对1/4-QPSK、8PSK信号进行识别。从理论上分析了的该算法的有效性，并通过计算机仿真验证了算法具有良好的性能。(A recognition algorithm based on differential high-order cumulant is proposed for the modulation recognition problems of BPSK, QPSK, 1/4-QPSK and 8PSK, which are commonly used in current communication signals. The algorithm is divided into two levels for modulation recognition. Firstly, BPSK, QPSK and {1/4-QPSK, 8PSK} signals are identified by using the fourth-order cumulant characteristics of signals, and then 1/4-QPSK and 8PSK signals are identified by using the fourth-order cumulant and eighth-order cumulant characteristics of signal difference. The validity of the algorithm is analyzed theoretically, and the good performance of the algorithm is verified by computer simulation.)
