OFDMcode
- OFDM信号的编码译码仿真，英文说明更详细。-This simulation scr ipt set allows for an OFDM transmission to be simulated. Imagetx.m generates the OFDM signal, saving it as a windows WAV file. This allows the OFDM signal to be played out a sound card and recorded b
read_wav
- 读进来WAV格式的语音数据，并绘制其波形，再播放WAV音频。-Reading into WAV format voice data, and mapping of its waveform, and WAV audio player.
OFDMcode
- OFDM系统仿真，包含了发射、信道估计、接受等完整的OFDM系统仿真-his simulation scr ipt set allows for an OFDM transmission to be simulated. Imagetx.m generates the OFDM signal, saving it as a windows WAV file. This allows the OFDM signal to be played out a sound card and recorde
audio_demo
- 语音信号处理：This package encloses a small application dedicated to speech signal processing at 8 kHz or 16 kHz. This application reads standard *.wav or *.pcm files through UI dialog box, plots and plays the signal with vertical dynamic crosshairs.-This
FIR_matlab
- 给定一个混有单频噪声的wav波形文件，设计一个滤波器，要求能很好的滤除掉单频噪声，并且对原声音信号的影响最小。这里仅仅要求FIR滤波器用窗函数法，IIR滤波器用butterworth实现。-FIR matlab filter butterworth
WaveHeaderRead
- matlab程序读取wav文件头，并显示文件基本信息-Read the header of .wav files and display the basic information of the file.
main2
- 使用Matlab,采用LPC线性预测编码对wav语音文件进行压缩编码-Using Matlab, using linear predictive coding LPC voice wav file compression
带阻数字滤波器
- 读入bluesky3.wav文件（内容为男生“蓝天，白云”），在语音数据中混入50Hz的交流声，设计一个用凯泽窗的带组数字滤波器，通带截止评率45Hz,带组截止频率49和51，阻带最小衰减A2=50dB,采样频率为8000Hz(Read the bluesky3.wav file (the content is for boys "blue sky, white clouds"), mix 50Hz hum into the voice data, design a band
