Review Analysis for Implementation of SC-FDMA over WiMAX Broadband Networks
Journal Title: INTERNATIONAL JOURNAL OF ENGINEERING TRENDS AND TECHNOLOGY - Year 2014, Vol 11, Issue 10
Abstract
WiMAX (Worldwide Interoperability for Microwaves Access) is a key technology which builds a base for next generation of mobile broadband networks. WiMAX and Long Term Evolution (LTE) standards are the two main contenders in the 4G wireless scenario. WiMAX air Interface adopts Orthogonal Frequency Division Multiple Access (OFDMA) for Uplink and Downlink transmission. Single Carrier Frequency Division Multiple Access, which utilizes single carrier modulation and frequency domain equalization is a technique which has similar performance and same overall complexity as those of OFDM, in which peak-to-average power ratio is a major drawback. The main advantage of SC-FDMA is its lower PAPR due to its single carrier structure. In this paper, we do a systematic analysis on the implementation of SC-FDMA in WiMAX PHY layer (UPLINK).
