Abstract

Orthogonal frequency division multiplexing (OFDM) is a reliable technology for high-speed data transmission by virtue of its spectral efficiency and robustness to multi-path fading. These advantages can be achieved only with good synchronization both in time and frequency. This paper introduces efficient synchronization methods for an OFDM based system, IEEE 802. 16d. A symbol timing synchronization scheme is critical in the design of an OFDM receiver. Large timing errors can result in loss of orthogonality between subcarrier, ISI and severe bit degradation. To minimize this degradation two kinds of synchronization algorithms are provided: Auto-correlation and cross correlation. This brief discusses these techniques used in synchronization of OFDM and which one is preferred.
