- W2371460856 abstract "A new synchronization scheme was proposed based on a new training sequence which is composed of two OFDM symbols with wide-sense repetition structure.After combining several auto-correlation peaks from two OFDM training symbols,this algorithm maintains a good estimation performance of time under a low system complexity.After combining the phase from auto-correlation with different delays,two initial estimations of the frequency offset corresponding to the two training symbols can be obtained.According to some knowledge on number theory,those two initial estimations jointly estimate the frequency offset with a quite large range.This algorithm operates in time domain,thus,it involves no FFT computation of the whole training sequence,leading to a low system complexity.The computer simulations show that by appropriately choosing the repetition number L,the scheme is able to deal with a relatively large range of frequency offset,while maintaining a good estimation performance." @default.
