Audio signal OFDM Modulation in Matlab (please help me)

[Alireza Nakhostin]

Hi My Frindes
I've designed transmitter - receiver Ofdm in MATLAB.
String of bits 0 and 1 will transfer well, but I am faced with the problem of transmitting sound.
I do not know, should be operational before the modulation using the instructions on how to do sound.
Please Help Me

Sorry if the description is not flowing

Hi

Before transmitting, you require data preparation which actually converts your sound files in stream of "0's" & "1's".
If you are using stereophonic sound then after reading into MATLAB , you will have two channel. This two channel needs to convert into streams of "0's" & "1's". For this you can use one variable as "Threshold" and set. you can get the value of threshlod from data itself by just using some formula.. lets say data > mean (channel1) / median (channel1) like that.

This ensures that data will convert into binary stream. Within Simulink there are blocks which will do this and similary to recover sound you again convertstreams of "0" & "1's" to sound data

Hope this will help you
