Abstract
A method for synchronization of an emitter of FBMC system with a RACH channel. On the emitter, a pseudo-random sequence with an initial offset in relation to a reference sequence is inserted into the spectral band of the RACH channel. On the receiver, the sequence received on the RACH channel is estimated using a sliding FFT using a starting point and correlated with the reference sequence. The position of the starting point leading to the highest correlation peak is selected as well as the correlation position corresponding to this peak, with these two positions making it possible to determine the offset of the sequence received with the reference sequence. This offset is transmitted to the emitter and the latter deduces from it a delay to be compensated in the emission in order to synchronize with the receiver.
