集成了C代码和MATLAB的主成分分析代码，可以用这两种方法解决求取特征值和特征向量。(C code and MATLAB integrates principal component analysis code, you can use two methods to solve strike eigenvalues ​ ​ and eigenvectors.)

matlab code for applying sharpening filters to image

此为：加权最小二乘法源码（使用最原始的的定义公式编码）(This is: weighted least squares method source code (using the original definition of the formula coding))

这是saleh提出其高功率放大器模型的原文 很难找 给大家共享(This is saleh to present its high-power amplifier model of the original hard to find for everyone to share)

实现分段拟合处理数据，达到实现文中的可调式程序的目的，实现了数据处理的可能性(Fitting the data to achieve piecewise)

Considered a 16QAM communication system. The information rate is 2 Mb/s and the carrier frequency is 12 GHz. Assumed perfect synchronization. a) Simulated the system if the channel is AWGN and draw bit error rate of the system versus Eb/No. Compare the results with what you obtain in theory. b) Considered (15,11) Hamming code. Apply this code into the above system. Compare the results with what you obtain in theory. c) Simulated uncoded system if we have a Doppler Spread due to mobile movement in the channel. Simulate and draw the bit error rate of the system for maximum mobile speed 42.3 Km/Hour. No equalizer is used in the system. d) Applied coding of part (b) into the system of part (c). Simulate the system and discuss the results. e) Designed an interleaver for the system of part (d) to improve the coded performance results. Simulated the system.
