Find local minimum in matlab

papr to differenrt number of subcarrier: we put N = 256,512,1024 and show the output ofp ccdf with papr when we use QPSK modulation. The PAPR ratio is a measure of the dynamic range in OFDM signals. Thus high PAPR induces a high dynamic range which describes high variability in the signal range. complex data sequences are input to the IDFT of an OFDM transmitter then at the output of the IDFT, real and imaginary parts are obtained.

说明：  运用粒子群算法自动修正BLDC的PID参数，视电脑情况需要运行一段时间才能出结果，可自己修改粒子群参数(The PID parameters of BLDC are automatically modified by particle swarm optimization algorithm, and the results can only be obtained after running for a period of time depending on the situation of the computer. You can modify the parameters of particle swarm by yourself)

说明：  每个传感器具有一定的范围和精度，而且周围环境可能对它们产生干扰。即单传感器只能提供部分不精确的信息，从而不能排除对外界环境描述的歧义性。鉴于各传感器性能上的差异表现出的互补性，如果综合各个传感器的信息，就能得到比单一传感器所能提供的更准确可靠的信息。简言之，与单一传感器相比，多传感器数据融合由于信息的冗余性和互补性存在很多方面的优势。 多传感器融合(Each sensor has a certain range and accuracy, and the surrounding environment may interfere with them. That is to say, a single sensor can only provide some inaccurate information, so it can not rule out the ambiguity of the description of the external environment. In view of the complementarity of the differences in the performance of each sensor, if we synthesize the information of each sensor, we can get more accurate and reliable information than a single sensor can provide. In short, compared with a single sensor, multi-sensor data fusion has many advantages due to the redundancy and complementarity of information.)
