Orthogonal Frequency Division Multiplexing (OFDM) is a multiplexing technique which is widely applied in wireless communication systems because of its high data rate transmission capability and high bandwidth efficiency. This paper presents a comprehensive survey on OFDM for wireless communications. This paper will first review basic OFDM modulation along with techniques to improve the performance of OFDM in wireless communication. The combination of Multiple-Input Multiple-Output (MIMO) and OFDM has the potential to address the problem of interference in modern communication systems and therefore particular emphasis is given to MIMO-OFDM.
