A matlab function to calculate the Planck function

包络曲线的求法 matlab中的一种求上下包络的算法，特别经典的两种算法(Envelope curve for France matlab down in one envelope seeking algorithms, especially the classic two algorithms)

七电平逆变器的Simulink模型，调制方式采用SPWM方式，拓扑为H桥级联。(The Simulink model of Seven-level inverters adopts SPWM modulation mode and H-bridge cascade topology.)

该程序完成一个16电平PAM数字通信系统的仿真，并测量了它的误码率。首先产生信息符号序列，该序列被当做4个信息比特一组，将16组符号映射到16个信息幅度。检测器计算距离，输出与真正传输的信息符号序列作比较，然后将差错计数。( This procedure completes a 16 level PAM digital communication system s simulation, and has surveyed its error rate. First has the message digit sequence, this sequence is treated as a 4 information bit group, maps 16 class symbols to 16 information scopes. The detector estimated range, the output and the true transmission s message digit sequence does compares, then counts the mistake. )
