How Many Sub Carrier in LTE? Read below,..There are different kinds of sub-carriers:

  1. Data sub-carrier
  2. Pilot Sub-carrier
  3. DC sub-carrier
  4. Guard Sub-carrier

DC stands for Direct Current and it is a subcarrier that has no information sent on it. This is an important


subcarrier in OFDM based systems. It is used by the mobile device to locate the center of the OFDM frequency band. So, if LTE does not have a DC subcarrier, it would be a big deal .
