Abstract： |
The method features the following: interpolating intensive frequency domain points into certain interval of OFDM symbol; at the receiving end, the optimal intercepting position is adjusted by using the drift of the initial time in the time-domain energy centralized area of the intensive frequency domain pilot frequency point so as to solve the problem of deviation existed in sendreceive crystal oscillator and to ensure the accurate time synchronization between the send and receiving ends. |
