I have a waveform from analog simulator, both time and voltage values are stored in a text file. The signal represented is a digital "1,0" stream.
What wanted in matlab processing is the digital information carried in. how to convert them into a stream of one zero (...)

I'm working on the project of data acquisition system in which using microcontroller I'm going to collect analog data, convert into digital and save those values in PC.
For sending values from microcontroller to PC I'm going to use matlab Serial communication...
The values will be sent continuously from controller to (...)

1). Do you have a block diagram of how the OFDM signals generated?
2) Do you have a simulation model (matlab,etc)? If so, try FFT the OFDM signals and have a look on the spectrum.
