Summary: 
This letter derives and computes the detection probability for timing synchronization in an orthogonal frequency division multiplexing (OFDM) system encountered with a multipath Rayleigh fading channel. OFDM timing synchronization using constant amplitude zero auto-correlation (CAZAC) training symbols and correlation techniques is adopted. With this provision, we focus on the numerical analysis for OFDM timing synchronization scheme employing a preadvancement technique to reduce the inter-symbol interference (ISI). For measuring system performance, the sync detection performance derived in the considered system is presented in a multipath Rayleigh fading channel.
