| () |
| Abstract: |
| A two - step algorithm combining with two classical algorithms is adopted, and an optimum algorithm with low complexity is presented for symbol, synchronization of OFDM systems. The algorithm is analyzed, simulated and compared combined with frequency -offset estimation. The simulation results show that the low -complexity symbol synchronization is not only precise but also simple. |
| Key words: OFDM symbol synchronization frequency - offset estimation algorithm |
