| Abstract: |
| A novel joint algorithm for timing and frequency offset estimation for OFDM systems is presented.Only one training symbol which is conjures and pair is used in timing recovery and carrier frequency estimation,the overhead is small.The performance of the proposed scheme is presented in terms of mean and standard deviation.The results show that the proposed estimation method is efficient. |
| Key words: OFDM,preamble,timing offset estimation,frequency offset estimation |
