Orthogonal Frequency Division Multiplexing (OFDM) is an emerging multi-carrier modulation scheme, which has been adopted for several wireless standards such as IEEE 802.11a and HiperLAN2. OFDM systems exhibit a sensitivity to phase noise higher than single carrier modulations due to its long symbol period. Because carriers are kept very close to each other, OFDM is very sensitive to distortion that may remove the orthogonality between carriers. Phase noise can cause several types of signal degradation that are usually very difficult to quantify analytically.
