In modern age, the service users of every network desire faster downloading speed/data rates so that they can watch live cricket, live video conferencing, IRCTC ticket booking etc. A technique known as OFDM is used to achieve faster speed. Orthogonal Frequency Division Multiplexing (OFDM) has been more popular for broadband wireless transmission due to its robustness against multipath fading. In OFDM system, orthogonally sub-carrier are used to carry the data from the transmitter end to the receiver end with the presence of guard band.
