| Abstract: | The principle of Orthogonal Frequency Division Modulation(OFDM) technology which is adaptive to high-data-rate transmission is summarized in this paper. And the focus is on the principle for implementing OFDM system with FFT in baseband and the solutions for carrier and symbol synchronization in OFDM. Then we end this paper with OFDM's application status in quo and its prospect in new information systems. |
| Keywords: | Data Transmission Multicarrier OFDM Multipath Time Delay Carrier and Symbol Synchronization Cyclic Extention |
