2ASK(1)通信系统仿真进行2ASK调制，其中基带信号为单极性NRZ矩形波，采用相干解调方法对带通滤波器的输出信号进行解调；(2ASK (1) 2ASK modulation for communication systems simulation, in which the baseband signal is unipolar NRZ square wave, coherent demodulation method using band-pass filter output signal demodulation )

OFDM峰均功率比的CCDF图，仿真10万个符号，结果曲线与理论相同(CCDF of PAPR for OFDM)

haning窗函数插值算法，可计算多次谐波信号的幅度相位和频率等信息。(haning window function interpolation algorithm to calculate multiple harmonic signal amplitude and phase and frequency information.)

这是实现MATLAB并行配置的技术资料，随着大数据时代的到来，越来越多的数据需要经过处理，并且目前的硬件已经满足不了这么多的数据的处理，因此并行计算成为了首选(This is the realization of technical information MATLAB parallel configuration, with the arrival of the era of big data, more data needs to be processed, and the current hardware has failed to meet so many data processing, parallel computing has become the preferred therefore)

求生物信号的滤波和归一化程序，是低频信号的在bp中应用的一部分。(Seeking biological signal filtering and normalization procedures, low-frequency signals in the bp part of the application.)

带汉明码的直接序列变换DSSS，直接序列变化中采用了hamm编码方式，带GUI(Hamming codes with the direct-sequence transform DSSS direct sequence changes hamm used in the encoding, with GUI)

实现轨道交通spirling计算 此软件简单易懂，所有的资料都在一个压缩包中，便于初学者使用(for spirling )

用matlab编制的机器人求逆以及求时间的程序，个人感觉很有应用借鉴价值。(using Matlab based robot inverse time and the procedures for seeking personal feeling good application reference value.)

说明：  在matlab编程中读入grd文件，绘制三维或者二维等值线图(grd)

说明：   已知某控制系统结构图如下所示,要求设计校正环节G(s),使系统对于阶跃输入的稳态误差为零。使系统校正后的相角裕量γ≥45°，幅值裕量kg≥10db。(Known structure of a control system as shown below, links to design correction G (s), allowing the system to step input for the steady-state error to zero. The system after correction phase margin γ ≥ 45 °, the amplitude margin kg ≥ 10db.)
