Timing synchronization for OFDM-based wireless networks |
摘要 |
Timing in a receiver is synchronized to an orthogonal frequency division multiplex (OFDM) signal transmitted over a channel. The OFDM signal includes multiple training symbols, including long and short training symbols. The first half of the training symbols are correlated with the second half to determine a coarse index which is used to adjust the unsynchronized OFDM. In the coursely adjusted OFDM signal, the first training symbol is then correlated with the last traininig symbol to determine a fine index to adjust the coarsely adjusted OFDM signal so that the receiver is synchronized with the transmitted OFDM signal.
