The goal for the next generation of mobile communications system is to seamlessly integrate a wide variety of communication services such as high speed data, video and multimedia traffic as well as voice signals. OFDM technique has been widely used in many wired and wireless multicarrier communication systems such as IEEE 802.11a, Digital Audio/Video Broadcasting (DAB/DVB), Asymmetric DSL (ADSL), and in upcoming technology-LTE (4G). OFDM is spectrally efficient and can provide high data rates with sufficient robustness to channel imperfections.
