Abstract

See full text

According to one embodiment, a synchronization circuit includes a received-signal detecting unit which detects a received signal including a first and a second reference signal, a timing-synchronization adjusting unit including a storage module storing information of the first reference signal and a correlation operating module carrying out correlation operation of the first reference signal included in the received signal and the information of the first reference signal output from the storage module, the timing-synchronization adjusting unit which carries out timing synchronization so that a result of the correlation operation carried out by the correlation operating module becomes a predetermined value, and a phase-synchronization adjusting unit which carries out phase synchronization of a subcarrier by adjusting a component varied depending on a phase of a subcarrier frequency by using a phase modulation signal included in the second reference signal, wherein the received signal is a filtered multicarrier signal.
