经典伪彩图，功率谱，很有意思，也很有用希望对大家有帮助。(typical power spectrum,very intresting,i hope everyone will love it.)

说明：  极化码编码中的scl译码算法，代码含有比较详细的注释(SCL decoding algorithm in polarization code coding with detailed comments)

一个用matlab实现的程序，将两幅图片叠加，其中附有叠加后的图片(The realization of a matlab procedure used to overlay two images, one with the picture after stacking)

采用LDPC编码对随机的二进制序列进行纠错编码和基带调制，在AWGN信道上进行传输，然后在接收端并采用合适的方式进行解调和译码，最后对纠错编码的性能加以分析。(LDPC codes using random binary sequence of error-correcting coding and base-band modulation, for transmission in the AWGN channel, and then at the receiving end and use the appropriate manner demodulation and decoding, error correction coding on the performance of the final analysis.)

matlab实现logistic回归 利用牛顿迭代的方法得到最后的回归参数(matlab realize logistic regression using Newton iteration method to get the final regression parameters)

adaptive spectrum sensing using SNAR comparioson and relative doppler shift (effect) between primary and secondary user

说明：  详细说明：语音信号的短时分析，主要包括：分帧、短时能量、短时平均幅度、短时过零率、短时自相关函数、短时幅度差、倒谱、复倒谱、lpc系数、lpc谱估计等 绝对保证质量，是保研后导师布置的一些基础程序(Details: short-time speech signal analysis, including: framing, short-term energy, short-term average rate, short-time zero crossing rate, short-time autocorrelation function, short-term magnitude difference, cepstrum, complex cepstrum, lpc coefficient, lpc absolute guarantee of the quality of spectral estimation, is the security arrangement of some of the research base after the mentor program)

说明：  BP算法是为了解决多层前向神经网络的权系数优化而提出来的；所以，BP算法也通常暗示着神经网络的拓扑结构是一种无反馈的多层前向网络(BP algorithm is to solve the multi-layer feedforward neural network weights optimization and put forward Therefore, BP algorithm usually implies that the topology of neural network is a multi-layer feedback-free network)

说明：  指派问题 微粒群PSO算法优化 带绘图 优化目标为工作质量(Assignment of particle swarm optimization PSO algorithm to optimize the drawing target with the quality of work)
