说明：  结构参数的线性拟合，用于多元参数的线性回归分析，最小二乘法。(multivariate linear fitness)

伪逆分类法的matlab实现，包含训练和测试部分(Pseudo-inverse classification matlab realization, including training and testing parts)

基于matlab的QPSK数字基带通信系统仿真(Matlab-based QPSK digital communication system simulation)

说明：  用matlab语言实现单频脉冲信号（CW）的时域波形、频域图像、模糊度图。(The time-domain waveform, frequency-domain image and ambiguity map of single frequency pulse signal (CW) are realized by MATLAB.)

根据LTE上行SIMO接收机特点，对MMSERISIC均衡器进行简化修改，得到MMSEFDE均衡器,该均衡器所有步骤全在频域进行，大大降低了均衡算法的复杂度。(LTE uplink SIMO receiver according to the characteristics of the MMSE-RISIC equalizer to simplify modification, by MMSE-FDE equalizer, the equalizer all the steps in full in the frequency domain, greatly reduces the complexity of balancing algorithm.)

一个降低OFDM峰均比的选择性映射的代码，将后面的压缩包格式去掉，本代码以WORD格式上传的(A lower PAPR OFDM selective mapping of code, will be behind the compressed packet format removed, the code to WORD format to upload)
