Abstract

There is considerable interest in the use of Single Carrier Frequency Division Multiple Access (SC-FDMA) as the uplink transmission scheme in the Third-generation Partnership Project-Long Term Evolution 3GPP-LTE standard. This interest is justified by the inherent single carrier structure of SC-FDMA, which results in reduced sensitivity to phase noise and a lower Peak-to-Average Power Ratio (PAPR) compared to Orthogonal Frequency Division Multiple Access OFDMA. This consequently makes it more attractive for low cost devices with limited transmit power. In this paper the LTE and SCFDMA specifications will be explained in details and the performance of the system will be examined under two types of equalization method which are zero forcing ZF and minimum mean square error MMSE method. Also the system was tested under two types of subcarrier mapping which are localized and distributed mapping in two types of channel models which are International Telecommunications Union (ITU) and Stanford University Interim (SUI). The results show that the system gives better performance with localized distributed mode and also give good performance with the minimum mean square error MMSE method and the system will give different response through the different channel cases.
