    Need Help: Subcarrier frequency in OFDM

    Thanks to Mityan and humourmind for your prompt reply. Now i need to use null subcarriers in ofdm. How can i use it. Actually i am confused because when we perform ifft on modulated symbol then we get ifft data and this data doesnt contain any null values. How can i use null subcarriers?
