使用同态滤波对图像进行对比度增强的处理，本代码仅适用于灰度图像。(Homomorphic filtering using the contrast of the image enhancement processing, the code applies only to grayscale.)

matlab的入门资料，内容丰富而且包含所有例程。入门学习的好材料！包括绘图，插值，拟合，线性规划，最优问题等等(easy to learn matlab,include all m file)

一个相对完整的OFDM通信系统的仿真设计，包括编码，调制，IFFT，上下变频，高斯信道建模，FFT，PAPR抑制，各种同步，解调和解码等模块，并统括系统性能的仿真验证了系统设计的可靠性。(Simulation and Design of a relatively complete OFDM communications system, including coding, modulation, IFFT, down conversion, Gaussian channel model, FFT, PAPR suppression, various synchronization, demodulation and decoding module and simulation of system performance omnibus the reliability of system design.)

产生伪随机二维码,使用的是Matlab中的Simulink，应该很好用的，用于系统辨识(PEBS generator)

基于matlab的正弦波波形显示仿真源代码(sinusoidal waveform simulation shows the source code)

信道估计,we will assume that the receiver knows your name, i.e., it knows s (and of course x). Based on this knowledge, the receiver will estimate h using the MVU and MMSE method (for the latter it is also assumed that the variance of the noise σ2 is known at the receiver).(Channel Estimation:we will assume that the receiver knows your name, i.e., it knows s (and of course x). Based on this knowledge, the receiver will estimate h using the MVU and MMSE method (for the latter it is also assumed that the variance of the noise σ2 is known at the receiver).)
