Kw. Kang et al., DECISION-DIRECTED MAXIMUM-LIKELIHOOD-ESTIMATION OF OFDM FRAME SYNCHRONIZATION OFFSET, Electronics Letters, 30(25), 1994, pp. 2153-2154
The authors propose a method to estimate the synchronisation offset fo
r orthogonal frequency division multiplexing (OFDM) frame alignment wi
thout resort to pilot tones. A decision-directed maximum-likelihood es
timation of frame synchronisation offset is derived, and the performan
ce of the proposed scheme is confirmed by computer simulation for QAM
systems.
