基于matalb/simulink的模糊PID控制仿真。波形良好。 包括常规PID控制与模糊PID的对比仿真，以及加入延时的系统仿真和加入干扰后的系统仿真，均已经过调试，波形结果很好。 大家可直接用于借鉴学习。(Fuzzy PID control simulation based on matalb/simulink. Good waveform. Including the conventional PID control and fuzzy PID contrast simulation, and adding delay system simulation and adding interference after the system simulation, have been debugging, waveform results are very good. We can learn from them directly.)

设计一个四用户的扩频通信系统，扩频增益为N=16，采用Walsh码进行直接序列扩频，BPSK调制，无线信道为AWGN信道。在接收端进行解扩，解调，判决，通过仿真得到其中一个用户的误比特率与信噪比的仿真结果。(Designed a four-user spread spectrum communication system, spreading gain for N = 16, using Walsh code Direct Sequence Spread Spectrum, BPSK modulation, AWGN channel for the wireless channel. At the receiving end for despreading, demodulation, judgments, through the simulation to be one of a user' s bit error rate and SNR of the simulation results.)

1st FIR filter is given and wee need to find 2nd FIR filter that meet magnitude complementary criterion. fminsearch is used for error minimization.
