METHOD AND APPARATUS OF FREQUENCY OFFSET-FREE FRAME SYNCHRONIZATION FOR HIGH ORDER QAM SIGNALS IN MODEM APPARATUS |
摘要 |
Provided is a method and apparatus for performing a frequency offset-free frame synchronization with respect to high order quadrature amplitude modulation (QAM) symbols in a modem apparatus. A method of performing a correlation-based frame synchronization using magnitudes of QAM symbols in a modem apparatus, may include: constructing a synchronization pattern using the magnitudes of the QAM symbols; sequentially calculating a magnitude of each of received signals based on a symbol unit to construct a received vector; and obtaining a frame synchronization based on a correlation between the received vector and the synchronization pattern.
