第四版prokias数字通信之配套代码第九章(source code(matlab )for prokias Digital Communication (4th edition))

说明：  对IS-95前向链路使用matlab仿真 仿真源程序(On the IS-95 forward link simulation using matlab simulation source)

本代码为查表模糊控制的MATLAB实现，可供老师讲课及初学者学习(The code for the MATLAB fuzzy control look-up table implementation of lectures for teachers and beginners)

BPSK调制解调加上LDPC信道编码解码。画出误码率曲线(BPSK modulation and demodulation and LDPC channel coding and decoding. Draw the curve of error rate)

构建的异步电动机MATLAB本体仿真模型(Asynchronous motor body building MATLAB simulation model)

频谱选取，一般用于后续向量机的诊断的特征。进行了频谱分析后对每个频带的能量进行分离开。(Spectral selection, generally for subsequent diagnostic feature vector machine. Spectrum analysis conducted after the energy of each frequency band to leave.)

详细的线性PCA计算过程，详细的线性PCA计算过程(The linear PCA detailed calculation process)

The function impulsive_noise generates non-gaussian noise with inputs of beta, gamma,and the power of noise is 1 in W or 0 in dB. The noise can be defined either real or complex. The other functions generate QAM symbol and insert a vector to another vetor with specific locations

3维拓扑优化计算算法，可用于初级拓扑优化学习和在此基础上进行拓展(3 d topology optimization algorithm can be used for primary topology optimization learning and expansion on this basis)

HHT谱计算程序，不是rilling版本，用改进的Hilbert变换，效果好一些，供大家参考。(HHT spectrum of the calculation procedures, rilling is not a version of the Hilbert transform used to improve the results better for your reference.)
