这个是我的毕业设计做的我觉得对大家还是有写用的，所以我给打击看看希望大家也给点意见。(this is my graduation design so I think people are still used to write, So, I hope to see you blow also points.)

基于前馈补偿的PID控制算法。可以通过设置M参数查看控制效果（M=2时误差平稳且接近0）。(Feedforward compensation based on the PID control algorithm. You can view the control parameters by setting the effect of M (M = 2 when the error is stable and close to 0).)

Implements 2D Gabor filter for images works on Matlab an image has to be first read and then converted as gray-scale before passing on to this function.

dct precoded SLM method for PAPR reduction High Peak to Average Power Ratio (PAPR) is still a most important challenge in Orthogonal Frequency Division Multiplexing (OFDM) system. In this paper, we propose a Discrete Cosine Transform (DCT) precoding based SLM technique for PAPR reduction in OFDM systems. This technique is based on precoding the constellation symbols with DCT precoder after the multiplication of phase rotation factor and before the Inverse Fast Fourier Transform (IFFT) in SLM-OFDM System.

可以利用malab产生不同的调制信号，包括bpsk,qpsk,fsk,msk,16qam,64qam.(Malab can generate different modulated signals, comprising bpsk, qpsk, fsk, msk, 16qam, 64qam.)

16QAM基带 在 AWGN 信道下的调制解调仿真程序 无信道编码(16QAM AWGN)

依次输入三个函数即可，若想修改全排列矩阵的大小，可在MATLAB中打开tianchongJ修改(Input function can be followed by three, if amendments to the whole matrix with the size, can be opened in MATLAB to amend tianchongJ)
