| Abstract: | Orthogonal Frequency Division Multiplexing (OFDM) is a multi-carrier broadband modulation technique. OFDM has a good performance in dealing with multi-path disturbance and Inter Symbol Interference (ISI) compare to simple digital systems and it is adaptive to high-data-rate wireless communication systems. This paper presents an overview of OFDM technique and its implementation scheme and making use of MATLAB to simulate the transmission performance of a Variable Bit Rate OFDM in 802.11a standards. |
