| Abstract: | Orthognal Frequency Division Multiplexing (OFDM) is a multi-carrier digital modulation technique for broad-band wireless communication. Because of good performance in dealing with multi-path disturbance and Inter Symbol Interference (ISI), it has been applied broadly in wireless access. This paper presents an overview of ODFM technique,then introduces key technique for OFDM communication system, finally simulates OFDM baseband transmission. |
