Abstract
The latest patents on the synchronization techniques in wireless OFDM communications systems are overviewed in this paper. The novel inventions and methods in those patents, which deal with the symbol timing synchronization, the carrier frequency synchronization as well as the sampling clock synchronization in either the continuous transmission mode or the burst packet transmission mode systems are introduced and analyzed. Based on the corresponding analysis, the technical forecast and the future developments for synchronization techniques in OFDM systems are discussed in the paper as well.
Keywords: continuous transmission mode, burst packet transmission mode, sampling clock synchronization, carrier frequency synchronization, symbol timing synchronization, OFDM
