Timing and Frequency Synchronization for OFDM Downlink Transmissions Using Zadoff-Chu Sequences

Orthogonal frequency division multiplexing (OFDM) technique has been widely adopted in wireless systems, but it is known for being sensitive to synchronization errors. In this paper, we present timing and frequency synchronization algorithms for OFDM downlink transmissions using Zadoff-Chu sequences...
