Good day everyone. I am currently doing my thesis on OFDM and my supervisor wants me to simulated continuous-time OFDM (i.e without using FFT). I've been able to simulate it using FFT but I have been unsuccessful in simulating the continuous-time OFDM. I would really appreciate it if anyone could help me out with the code. Thanks

Do you have a specific question? Normally it means to superimpose a low frequency signal onto a high frequency signal. A common example is you car radio. On the AM band, they modulate a signal in the megahertz range with an audio signal in the kilohertz range. That is because a megahertz signal becomes a radio wave which will propagate thru free space to your car when imposed on an antenna. This magic can be done with a simple multiplier for AM modulation. On your FM band, the same thing happens but the high frequency signal is in the 100's of megahertz. The FM modulator shifts the frequency up and down as the audio signal changes its level up and down. FM is much more immune to static since Mother Nature has a hard time doing FM modulation but has no problem doing AM herself as in lightning strikes. In the frequency domain, AM produces sum and difference frequencies. FM gets a little complicated. Charan does an elegant job of explaining it. Sorry if this was all a little simplistic I wanted to show off my ham radio experience. ;D

Hi All,
I am doing a project called "OFDM &QAM modulation for power line comunication and simulation on matlab".Can anybody help me with Matlab code.Please send me all info you have.I have been trying hard from 4 months now but couldn't get thru it.I need code for QAM&OFDM
thank you in advance.
hope you have a wonderful day ahead.

You need to read the tutorials. There is no other way to learn this. There is no one line explanation for modulation.
