The rapid advancement in the field of wireless communications that has been expedited by the commercial demand for better services has led to the application of wireless systems in many fields of life including education, military, medical and many real time services which demand a high data rate. OFDM is a promising technique that can provide this high data rate by efficiently utilizing the bandwidth. Thus a no. of emerging wireless standards such as 802.11n (Wi-Fi) and 802.16e (WiMax) use OFDM for increased spectral efficiency. The problem with OFDM is the high Inter-Carrier Interference...
