Example Embodiment
[0052] After careful observation, the inventor noticed that in the multipath channel, the arrival of each path will change the delay autocorrelation value of the input signal. When the last path arrives, the autocorrelation value will reach the maximum and form A platform does not change anymore. Therefore, a timing synchronization receiving method and device according to an embodiment of the present invention are proposed to realize the timing synchronization receiving of the PN sequence-based OFDM system. The basic idea is to determine the normalization of the input signal. Whether the modified delay autocorrelation value reaches the peak, and whether it forms a platform to determine whether the last path has arrived.
[0053] The present invention will be described in detail below with reference to the drawings.
[0054] reference figure 1 This figure shows a timing synchronization receiving method according to an embodiment of the present invention, which specifically include...
