Abstract(in English) | This paper proposes a new subcarrier synchronization method for OFDM signal, which is based on a periodical insertion of PN sequence in the time domain. In this system, a complex delay profile can be measured by the auto-correlation of DS/SS signal in the time domain. Then the phase of each subcarrier is synchronized using this delay profile. In the multi-carrier modulation, all delay waves may exist in the guard interval, so it is enough to observe the delay profile only in the guard interval. As a result, the proposed system achieve higher transmission efficiency. Computer simulation results show that the proposed system can achieve a smart subcarrier recovery under frequency selective Rayliegh fading. |
