A Blind Uplink OFDM Synchronization Algorithm Based on Cyclostationarity
SS Lab · Signal Processing · 2006
A blind uplink synchronization algorithm of multiuser OFDM is introduced in this article. Exploiting the second-order cyclostationarity and conjugate cyclostationarity of the received signal, the algorithm estimates the frequency offset and time delay of the channel. High resolution of the estimation as well as immunity to the noise and interference can be achieved, which is supported by the simulation results and comparison with other algorithm.
