Timing Synchronization in High Mobility OFDM Systems.IEEE Journal

It s a IEEE paper.In this paper,the author proposed two new frequency synchronization unsing PN sequences for OFDM system.

Application of spread spectrum for satellite land mobile systems is difficult in satellite link because of synchronization and providing code or considerable Doppler shift. This is particularly high for LEO satellites. So that, a Doppler shift carr

In this letter, we propose a simple orthogonal frequency-division multiplexing (OFDM) scheme for an asynchronous cooperative system, where OFDM is implemented at the source node, and time-reversion and complex conjugation are implemented at the rel
