This is the second part of special handling, that makes PTRACE_LDT possible to implement.

直流微网继电保护策略实现S-function的M文件，主保护为母线直流差动保护，基于小波分解的高频故障电流保护，后备保护为过电流保护，针对系统为2进2出的微网，只需将电流值输入，其中第一个输入变量为开关，为保护算法控制开始/关闭。(The relay protection strategy of DC microgrid realizes the M file of S-function. The main protection is busbar DC differential protection. The high frequency fault current protection based on wavelet decomposition and the backup protection is overcurrent protection. For the microgrid with 2 in and 2 out of the system, only the current value is input. The first input variable is switch, which starts/closes for the control of the protection algorithm.)

说明：  基于matlab中的simulink，进行16QAM的仿真搭建。包括了基带信号发生器，串/并模块，模块1，载波调制模块，高斯白噪声信道，模块2，误码率计算器等，能够较好地实现16QAM的调制解调。(Based on the Simulink of MATLAB, the simulation of 16QAM is built. It includes baseband signal generator, serial / parallel module, module 1, carrier modulation module, Gaussian white noise channel, module 2, bit error rate calculator and so on. It can achieve 16QAM modulation and demodulation well.)
