Description: This simulation script 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 back. Imagerx.m decodes the WAV to extract the
data.
settings.m contains all the common settings to specify all the
simulation parameters such as FFT size, number of carriers,
input data source file, input and output WAV files, etc.

Description: OFDM信号的编码译码仿真，英文说明更详细。-This simulation script 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 back. Imagerx.m decodes the WAV to extract the
data.
settings.m contains all the common settings to specify all the
simulation parameters such as FFT size, number of carriers,
input data source file, input and output WAV files, etc.
See settings.m for more details.
Note: The both the receiver and transmitter must have a copy of the
input data file, as this is used for calculating the exact number
of data words in the transmission.
The scripts should work as extracted. Just run imagetx.m to generate the
OFDM signal. Then run imagerx.m to decode the signal. The initial settings
transmit a wave file Corrs.wav . The decoded OFDM data ( Out.wav ) can be
compared with the original data by listening to the two wave files. Platform: |

Description: 将背景音乐（交响乐）中的摩斯电码找出并分离出来-morse_code_sound.wav is a mono (1-channel) 11,025 samples per sec, 16-bits per sample, WAV file. There is a morse code signal within the audio file, you should be able to hear it in the background, but it is not very audible (able to be heard). Write a Matlab program to analyze the wav file and determine the narrow range of frequencies occupied by the morse code sound. Then separate the morse code sound into a separate file and the music into a separate file. Write out the separated morse code and the separated music to separate wav files titled your_name_morse.wav and your_name_music.wav Platform: |
