Frequency offset correction in the presence of intersymbol interference |
| 摘要 |
<p>In order to allow frequency offset estimation even in the presence of intersymbol interference, it is proposed to use an impulse response shortening filter. The receiver extracts two known subsequences from the received signal, and compares their phases, in order to estimate the frequency offset.</p> |
