At present, only low rate data services are available for mobile applications. However, there is a demand for high data rates for multimedia applications. In single carrier system, the symbol duration reduces with an increase in data rate. Therefore, multicarrier transmission is a way to increase the data rate. Multicarrier modulation, and especially OFDM, is one of the promising candidates that employ a set of subcarriers in order to transmit the information symbols in parallel over the communication channel. OFDM is the key technology of 4th generation wireless communication.
