Abstract
In this article, we propose a blind synchronization algorithm for the uplink OFDMA system. The algorithm exploits the second-order cyclostationarity of the received signal, to estimate the frequency offset and time delay under the different subcarrier allocation schemes. The performance of high resolution and immune to the effect of noise and interference is evaluated through simulation results.
