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.)

说明：  AWGN信道下，fqpsk 调制的MAP检测 (under awgn channel,MAP demodulation for FQPSK modulation)

关于matlab的一些程序，比如各种滤波器设计(some program about matalb,such as kinds of filter s design)

matlab编的lqr控制三层结构的在地震作用下的响应(matlab series LQR control the response of the three-tier structure under seismic action)

cstr状态反馈预测控制模型 matlab中S函数建立(cstr state feedback model predictive control matlab function in the establishment of S)

说明：  这是个基于matlab环境下，提取mfcc参数的小程序，希望能对大家有帮助。(This is a matlab-based environment, the applet parameter extraction mfcc, hoping to be helpful.)

单极性PWM控制方式Simulink仿真，很简单，便于电力电子初初学入门者学习，里面还加了一个模拟滤波器，也很简单，但想法非常重要 (Unipolar PWM control mode Simulink simulation is very simple, easy beginner beginners to learn the beginning of the power electronics, which also added an analog filter is also very simple, but the idea is very important)
