OFDM_matlab

Flood fill, also called seed fill, is an algorithm that determines the area connected to a given node in a multi-dimensional array. implementation in matlab

编写的是2-4进制转换的功能函数，而进制转化是进行QAM调制的必须元件，而且可根据次程序进行编写其他进制的转换(hexTransform is necessary to modulation for example MQAM)

this is an application of qrs detection. (pan tompkins)

OFDM的设计原理，还有matlab code(The design principle of OFDM, as well as matlab code)

matlab的教程，例题，包括数值，符号，图像等运算及答案(matlab tutorials, sample questions, including the values, symbols, images and other computing and answers)

Simulation for one leg hopping robot, testing or learning purposes only

说明：  利用小波变换实现对故障信号的特征提取 构造特征向量(Wavelet transform feature extraction of fault signals structural feature vector)

语音信号的维纳滤波，频域实现和时域实现方法(Wiener filtering of speech signals, frequency domain implementation and time domain implementation)

说明：  该项目用于通过使用导频序列（训练序列）和信道抽头来估计OFDM中存在的信道。使用BER曲线比较系统的性能，该BER曲线是针对均匀间隔的飞行员和紧密间隔的飞行员获得的。此外，通道抽头的数量也有所不同，以估算最佳的BER曲线(This project is used to estimate the channel in OFDM by using pilot sequence (training sequence) and channel tap. The BER curve is used to compare the performance of the system, which is obtained for pilots with uniform interval and pilots with tight interval. In addition, the number of channel taps varies to estimate the best BER curve)

改变图像的灰度级数，通过输入的数值确定灰度级(change degree of gray )
