| () |
| Abstract: |
| According to the preamble structure of IEEE802. 11a and the characters of short training symbols, the received output sequences and short training symbols are correlated. Mathematical methods for OFDM symbol timing can be confirmed from the correlating peak . The simulation result shows that this algorithm can overcome the influence of noise and get exact symbol timing. |
