A Differential Cross-Correlation Cell Search Algorithm for IEEE 802.16e OFDMA Systems

A differential cross-correlation cell ID identification algorithm is proposed for IEEE 802.16e OFDMA cellular system. First, we construct the downlink (DL) preamble structure and signal model with carrier frequency offset (CFO) and channel effects. Next, in order to achieve the initial synchronizati...

Summary:A differential cross-correlation cell ID identification algorithm is proposed for IEEE 802.16e OFDMA cellular system. First, we construct the downlink (DL) preamble structure and signal model with carrier frequency offset (CFO) and channel effects. Next, in order to achieve the initial synchronization, a differential receiver with cross correlation for all preamble patterns is proposed to search cell ID. Simulation results confirm that the proposed structure is suitable for ITU fading channels and outperforms the conventional cell search system.
